I am trying to launch chrome with an URL, the browser launches and it does nothing after that.
I am seeing the below error after 1 minute:
Unable to open browser with url: 'https://www.google.com' (Root cause: org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
(Driver info: chromedriver=2.39.562718 (9a2698cba08cf5a471a29d30c8b3e12becabb0e9),platform=Windows NT 10.0.15063 x86_64) (WARNING: The server did not provide any stacktrace information)
My configuration:
Chrome : 66
ChromeBrowser : 2.39.56
P.S everything works fine in Firefox
Thumb rule
A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing --no-sandbox flag when creating your WebDriver session, such a configuration is unsupported and highly discouraged. You need to configure your environment to run Chrome as a regular user instead.
This error message...
org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Your code trials and the versioning information of all the binaries would have given us some hint about what's going wrong.
However as per Add --disable-dev-shm-usage to default launch flags seems adding the argument --disable-dev-shm-usage will temporary solve the issue.
If you desire to initiate/span a new Chrome Browser session you can use the following solution:
System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized"); // open Browser in maximized mode
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model
WebDriver driver = new ChromeDriver(options);
driver.get("https://google.com");
disable-dev-shm-usage
As per base_switches.cc disable-dev-shm-usage seems to be valid only on Linux OS:
#if defined(OS_LINUX) && !defined(OS_CHROMEOS)
// The /dev/shm partition is too small in certain VM environments, causing
// Chrome to fail or crash (see http://crbug.com/715363). Use this flag to
// work-around this issue (a temporary directory will always be used to create
// anonymous shared memory files).
const char kDisableDevShmUsage[] = "disable-dev-shm-usage";
#endif
In the discussion Add an option to use /tmp instead of /dev/shm David mentions:
I think it would depend on how are /dev/shm and /tmp mounted.
If they are both mounted as tmpfs I'm assuming there won't be any difference.
if for some reason /tmp is not mapped as tmpfs (and I think is mapped as tmpfs by default by systemd), chrome shared memory management always maps files into memory when creating an anonymous shared files, so even in that case shouldn't be much difference. I guess you could force telemetry tests with the flag enabled and see how it goes.
As for why not use by default, it was a pushed back by the shared memory team, I guess it makes sense it should be useing /dev/shm for shared memory by default.
Ultimately all this should be moving to use memfd_create, but I don't think that's going to happen any time soon, since it will require refactoring Chrome memory management significantly.

Here is the link to the Sandbox story.
I started seeing this problem on Monday 2018-06-04. Our tests run each weekday. It appears that the only thing that changed was the google-chrome version (which had been updated to current) JVM and Selenium were recent versions on Linux box ( Java 1.8.0_151, selenium 3.12.0, google-chrome 67.0.3396.62, and xvfb-run).
Specifically adding the arguments "--no-sandbox" and "--disable-dev-shm-usage" stopped the error.
I'll look into these issues to find more info about the effect, and other questions as in what triggered google-chrome to update.
ChromeOptions options = new ChromeOptions();
...
options.addArguments("--no-sandbox");
options.addArguments("--disable-dev-shm-usage");
We were having the same issues on our jenkins slaves (linux machine) and tried all the options above.
The only thing helped is setting the argument
chrome_options.add_argument('--headless')
But when we investigated further, noticed that XVFB screen doesn't started property and thats causing this error. After we fix XVFB screen, it resolved the issue.
I had the same problem in python. The above helped. Here is what I used in python -
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome('/path/to/your_chrome_driver_dir/chromedriver',chrome_options=chrome_options)
I was facing the same issue recently and after some trial and error it worked for me as well.

In my case in the following environment:
Windows 10
Python 3.7.5
Google Chrome version 80 and corresponding ChromeDriver in the path C:\Windows
selenium 3.141.0
I needed to add the arguments --no-sandbox and --remote-debugging-port=9222 to the ChromeOptions object and run the code as administrator user by lunching the Powershell/cmd as administrator.
Here is the related piece of code:
options = webdriver.ChromeOptions()
options.add_argument('headless')
options.add_argument('--disable-infobars')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--no-sandbox')
options.add_argument('--remote-debugging-port=9222')
driver = webdriver.Chrome(options=options)
I ran into this problem on Ubuntu 20 with Python Selenium after first downloading the chromedriver separately and then using sudo apt install chromium-browser Even though they were the same version this kept happening.
My fix was to use the provided chrome driver that came with the repo package located at
/snap/bin/chromium.chromedriver
driver = webdriver.Chrome(chrome_options=options, executable_path='/snap/bin/chromium.chromedriver')
Update:
I am able to get through the issue and now I am able to access the chrome with desired url.
Results of trying the provided solutions:
I tried all the settings as provided above but I was unable to resolve the issue
Explanation regarding the issue:
As per my observation DevToolsActivePort file doesn't exist is caused when chrome is unable to find its reference in scoped_dirXXXXX folder.
Steps taken to solve the issue
I have killed all the chrome processes and chrome driver processes.
Added the below code to invoke the chrome
System.setProperty("webdriver.chrome.driver","pathto\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(options);
driver.get(url);
Using the above steps I was able to resolve the issue.
Thanks for your answers.
In my case it was problem with CI Agent account on ubuntu server, I solved this using custom --user-data-dir
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
My account used by CI Agent didn't have necessary permissions, what was interesting everything was working on root account
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--profile-directory=Default')
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
driver = webdriver.Chrome(options=chrome_options)
url = 'https://www.google.com'
driver.get(url)
get_url = driver.current_url
print(get_url)
There is lot of possible reasons for the RESPONSE InitSession ERROR unknown error: DevToolsActivePort file doesn't exist error message (as we can see from the number of answers for this question). So let's dive deeper to explain what exactly this error message means.
According to chromedriver source code the message is created in ParseDevToolsActivePortFile method. This method is called from the loop after launching chrome process.
In the loop the driver check if the chrome process is still running and if the ParseDevToolsActivePortFile file was already created by chrome. There is a hardcoded 60s timeout for this loop.
I see two possible reasons for this message:
Chrome is really slow during startup - for example due to lack of system resources - mainly CPU or memory. In this case it can happen that sometimes chrome manage to start in time limit and sometimes not.
There is another issue which prevents chrome to start - missing or broken dependency, wrong configuration etc. In such case this error message is not really helpful and you should find another log message which explain the true reason of the failure.
It happens when chromedriver fails to figure out what debugging port chrome is using.
One possible cause is an open defect with HKEY_CURRENT_USER\Software\Policies\Google\Chrome\UserDataDir
But in my last case, it was some other unidentified cause.
Fortunately setting port number manually worked:
final String[] args = { "--remote-debugging-port=9222" };
options.addArguments(args);
WebDriver driver = new ChromeDriver(options);
As stated in this other answer:
This error message... implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Among the possible causes, I would like to mention the fact that, in case you are running an headless Chromium via Xvfb, you might need to export the DISPLAY variable: in my case, I had in place (as recommended) the --disable-dev-shm-usage and --no-sandbox options, everything was running fine, but in a new installation running the latest (at the time of writing) Ubuntu 18.04 this error started to occurr, and the only possible fix was to execute an export DISPLAY=":20" (having previously started Xvfb with Xvfb :20&).
You can get this error simply for passing bad arguments to Chrome. For example, if I pass "headless" as an arg to the C# ChromeDriver, it fires up great. If I make a mistake and use the wrong syntax, "--headless", I get the DevToolsActivePort file doesn't exist error.
I was stuck on this for a very long time and finally fixed it by adding this an additional option:
options.addArguments("--crash-dumps-dir=/tmp")
I know it's an old question and it already has a lot of answers. However, I ran into this issue, bumped into this thread and none of the proposed solutions helped. After spending a few days(!) on it I finally found a solution:
My problem was that I was using the selenium/standalone-chrome image on a MacBook with M1 chip. After switching to seleniarm/standalone-chromium everything finally started to work.
I had the same issue, but in my case chrome previously was installed in user temp folder, after that was reinstalled to Program files. So any of solution provided here was not help me. But if provide path to chrome.exe all works:
chromeOptions.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
I hope this helps someone =)
In my case it happened when I've tried to use my default user profile:
...
options.addArguments("user-data-dir=D:\\MyHomeDirectory\\Google\\Chrome\\User Data");
...
This triggered chrome to reuse processes already running in background, in such a way, that process started by chromedriver.exe was simply ended.
Resolution: kill all chrome.exe processes running in background.
update capabilities in conf.js as
exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['todo-spec.js'],
capabilities: {
browserName: 'chrome',
chromeOptions: {
args: ['--disable-gpu', '--no-sandbox', '--disable-extensions', '--disable-dev-shm-usage']
}
},
};
Old question but a similar issue nearly drove me to insanity so sharing my solution. None of the other suggestions fixed my issue.
When I updated my Docker image Chrome installation from an old version to Chrome 86, I got this error. My setup was not identical but we were instantiating Chrome through a selenium webdriver.
The solution was to pass the options as goog:chromeOptions hash instead of chromeOptions hash. I truly don't know if this was a Selenium, Chrome, Chromedriver, or some other update, but maybe some poor soul will find solace in this answer in the future.
For Ubuntu 20 it did help me to use my systems chromium driver instead of the downloaded one:
# chromium which
/snap/bin/chromium
driver = webdriver.Chrome('/snap/bin/chromium.chromedriver',
options=chrome_options)
And for the downloaded webdriver looks like it needs the remote debug port --remote-debugging-port=9222 to be set, as in one of the answers (by Soheil Pourbafrani):
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--remote-debugging-port=9222")
driver = webdriver.Chrome('<path_to>/chromedriver', options=chrome_options)
Date 9/16/2021
Everything works fine running chrome with selenium locally with python inside the docker hosted ubuntu container. When attempting to run from Jenkins the error above is returned WebDriverException: unknown error: DevToolsActivePort
Environment:
-Ubuntu21.04 inside a docker container with RDP access.
-chromedriver for chrome version: 93
Solution:
Inside the python file that starts the browser I had to set the DISPLAY environment variable using the following lines:
import os
os.environ['DISPLAY'] = ':10.0'
#DISPLAY_VAR = os.environ.get('DISPLAY')
#print("DISPLAY_VAR:", DISPLAY_VAR)
In my case, I was trying to create a runnable jar on Windows OS with chrome browser and want to run the same on headless mode in unix box with CentOs on it. And I was pointing my binary to a driver that I have downloaded and packaged with my suite. For me, this issue continue to occur irrespective of adding the below:
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
System.setProperty("webdriver.chrome.args", "--disable-logging");
System.setProperty("webdriver.chrome.silentOutput", "true");
options.setBinary("/pointing/downloaded/driver/path/in/automationsuite");
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("window-size=1024,768"); // Bypass OS security model
options.addArguments("--log-level=3"); // set log level
options.addArguments("--silent");//
options.setCapability("chrome.verbose", false); //disable logging
driver = new ChromeDriver(options);
Solution that I've tried and worked for me is, download the chrome and its tools on the host VM/Unix box, install and point the binary to this in the automation suite and bingo! It works :)
Download command:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
Install command:
sudo yum install -y ./google-chrome-stable_current_*.rpm
Update suite with below binary path of google-chrome:
options.setBinary("/opt/google/chrome/google-chrome");
And.. it works!
I also faced this issue while integrating with jenkins server, I was used the root user for jenkin job, the issue was fixed when I changed the user to other user. I am not sure why this error occurs for the root user.
Google Chrome Version 71.0
ChromeDriver Version 2.45
CentOS7 Version 1.153
I run selenium tests with Jenkins running on an Ubuntu 18 LTS linux. I had this error until I added the argument 'headless' like this (and some other arguments):
ChromeOptions options = new ChromeOptions();
options.addArguments("headless"); // headless -> no browser window. needed for jenkins
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model
ChromeDriver driver = new ChromeDriver(options);
driver.get("www.google.com");
Had the same issue. I am running the selenium script on Google cloud VM.
options.addArguments("--headless");
The above line resolved my issue. I removed the other optional arguments. I think the rest lines of code mentioned in other answers did not have any effect on resolving the issue on the cloud VM.
in my case, when i changed the google-chrome and chromedriver version, the error was fixed :)
#google-chrome version
[root#localhost ~]# /usr/bin/google-chrome --version
Google Chrome 83.0.4103.106
#chromedriver version
[root#localhost ~]# /usr/local/bin/chromedriver -v
ChromeDriver 83.0.4103.14 (be04594a2b8411758b860104bc0a1033417178be-refs/branch-heads/4103#{#119})
ps: selenium verison was 3.9.1
No solution worked for my. But here is a workaround:
maxcounter=5
for counter in range(maxcounter):
try:
driver = webdriver.Chrome(chrome_options=options,
service_log_path=logfile,
service_args=["--verbose", "--log-path=%s" % logfile])
break
except WebDriverException as e:
print("RETRYING INITIALIZATION OF WEBDRIVER! Error: %s" % str(e))
time.sleep(10)
if counter==maxcounter-1:
raise WebDriverException("Maximum number of selenium-firefox-webdriver-retries exceeded.")
It seems there are many possible causes for this error. In our case, the error happened because we had the following two lines in code:
System.setProperty("webdriver.chrome.driver", chromeDriverPath);
chromeOptions.setBinary(chromeDriverPath);
It's solved by removing the second line.
I ran into same issue, i am using UBUNTU, PYTHON and OPERA browser. in my case the problem was originated because i had an outdated version of operadriver.
Solution:
1. Make sure you install latest opera browser version ( do not use opera beta or opera developer), for that go to the official opera site and download from there the latest opera_stable version.
Install latest opera driver (if you already have an opera driver install, you have to remove it first use sudo rm ...)
wget https://github.com/operasoftware/operachromiumdriver/releases/download/v.80.0.3987.100/operadriver_linux64.zip
unzip operadriver_linux64.zip
sudo mv operadriver /usr/bin/operadriver
sudo chown root:root /usr/bin/operadriver
sudo chmod +x /usr/bin/operadriver
in my case latest was 80.0.3987 as you can see
Additionally i also installed chromedriver (but since i did it before testing, i do not know of this is needed) in order to install chromedriver, follow the steps on previous step :v
Enjoy and thank me!
Sample selenium code
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Opera()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.quit()
I came across the same problem, in my case there are two different common user userA and userB in Linux system.
userA first run the selinium programe which start chrome browswer with ChromeDriver successfully, when it came to userB, the DevToolsActivePort file doesn't exist error occur.
I tried the --remote-debugging-port=9222 option, but it lead to a new exception:
selenium.common.exceptions.WebDriverException: Message: chrome not reachable
The I ran google-chome directory and see the following error:
mkdir /tmp/Crashpad/new: Permission denied (13)
The I search the problem and got this:
https://johncylee.github.io/2022/05/14/chrome-headless-%E6%A8%A1%E5%BC%8F%E4%B8%8B-devtoolsactiveport-file-doesn-t-exist-%E5%95%8F%E9%A1%8C/

In my case in the following environment:
Windows 10
Python 3.7.5
Google Chrome version 80 and corresponding ChromeDriver in the path C:\Windows
selenium 3.141.0
I needed to add the arguments --no-sandbox and --remote-debugging-port=9222 to the ChromeOptions object and run the code as administrator user by lunching the Powershell/cmd as administrator.
Here is the related piece of code:
options = webdriver.ChromeOptions()
options.add_argument('headless')
options.add_argument('--disable-infobars')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--no-sandbox')
options.add_argument('--remote-debugging-port=9222')
driver = webdriver.Chrome(options=options)
I ran into this problem on Ubuntu 20 with Python Selenium after first downloading the chromedriver separately and then using sudo apt install chromium-browser Even though they were the same version this kept happening.
My fix was to use the provided chrome driver that came with the repo package located at
/snap/bin/chromium.chromedriver
driver = webdriver.Chrome(chrome_options=options, executable_path='/snap/bin/chromium.chromedriver')
Update:
I am able to get through the issue and now I am able to access the chrome with desired url.
Results of trying the provided solutions:
I tried all the settings as provided above but I was unable to resolve the issue
Explanation regarding the issue:
As per my observation DevToolsActivePort file doesn't exist is caused when chrome is unable to find its reference in scoped_dirXXXXX folder.
Steps taken to solve the issue
I have killed all the chrome processes and chrome driver processes.
Added the below code to invoke the chrome
System.setProperty("webdriver.chrome.driver","pathto\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(options);
driver.get(url);
Using the above steps I was able to resolve the issue.
Thanks for your answers.
In my case it was problem with CI Agent account on ubuntu server, I solved this using custom --user-data-dir
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
My account used by CI Agent didn't have necessary permissions, what was interesting everything was working on root account
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--profile-directory=Default')
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
driver = webdriver.Chrome(options=chrome_options)
url = 'https://www.google.com'
driver.get(url)
get_url = driver.current_url
print(get_url)
There is lot of possible reasons for the RESPONSE InitSession ERROR unknown error: DevToolsActivePort file doesn't exist error message (as we can see from the number of answers for this question). So let's dive deeper to explain what exactly this error message means.
According to chromedriver source code the message is created in ParseDevToolsActivePortFile method. This method is called from the loop after launching chrome process.
In the loop the driver check if the chrome process is still running and if the ParseDevToolsActivePortFile file was already created by chrome. There is a hardcoded 60s timeout for this loop.
I see two possible reasons for this message:
Chrome is really slow during startup - for example due to lack of system resources - mainly CPU or memory. In this case it can happen that sometimes chrome manage to start in time limit and sometimes not.
There is another issue which prevents chrome to start - missing or broken dependency, wrong configuration etc. In such case this error message is not really helpful and you should find another log message which explain the true reason of the failure.
It happens when chromedriver fails to figure out what debugging port chrome is using.
One possible cause is an open defect with HKEY_CURRENT_USER\Software\Policies\Google\Chrome\UserDataDir
But in my last case, it was some other unidentified cause.
Fortunately setting port number manually worked:
final String[] args = { "--remote-debugging-port=9222" };
options.addArguments(args);
WebDriver driver = new ChromeDriver(options);
As stated in this other answer:
This error message... implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Among the possible causes, I would like to mention the fact that, in case you are running an headless Chromium via Xvfb, you might need to export the DISPLAY variable: in my case, I had in place (as recommended) the --disable-dev-shm-usage and --no-sandbox options, everything was running fine, but in a new installation running the latest (at the time of writing) Ubuntu 18.04 this error started to occurr, and the only possible fix was to execute an export DISPLAY=":20" (having previously started Xvfb with Xvfb :20&).
You can get this error simply for passing bad arguments to Chrome. For example, if I pass "headless" as an arg to the C# ChromeDriver, it fires up great. If I make a mistake and use the wrong syntax, "--headless", I get the DevToolsActivePort file doesn't exist error.
I was stuck on this for a very long time and finally fixed it by adding this an additional option:
options.addArguments("--crash-dumps-dir=/tmp")
I know it's an old question and it already has a lot of answers. However, I ran into this issue, bumped into this thread and none of the proposed solutions helped. After spending a few days(!) on it I finally found a solution:
My problem was that I was using the selenium/standalone-chrome image on a MacBook with M1 chip. After switching to seleniarm/standalone-chromium everything finally started to work.
I had the same issue, but in my case chrome previously was installed in user temp folder, after that was reinstalled to Program files. So any of solution provided here was not help me. But if provide path to chrome.exe all works:
chromeOptions.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
I hope this helps someone =)
In my case it happened when I've tried to use my default user profile:
...
options.addArguments("user-data-dir=D:\\MyHomeDirectory\\Google\\Chrome\\User Data");
...
This triggered chrome to reuse processes already running in background, in such a way, that process started by chromedriver.exe was simply ended.
Resolution: kill all chrome.exe processes running in background.
update capabilities in conf.js as
exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['todo-spec.js'],
capabilities: {
browserName: 'chrome',
chromeOptions: {
args: ['--disable-gpu', '--no-sandbox', '--disable-extensions', '--disable-dev-shm-usage']
}
},
};
Old question but a similar issue nearly drove me to insanity so sharing my solution. None of the other suggestions fixed my issue.
When I updated my Docker image Chrome installation from an old version to Chrome 86, I got this error. My setup was not identical but we were instantiating Chrome through a selenium webdriver.
The solution was to pass the options as goog:chromeOptions hash instead of chromeOptions hash. I truly don't know if this was a Selenium, Chrome, Chromedriver, or some other update, but maybe some poor soul will find solace in this answer in the future.
For Ubuntu 20 it did help me to use my systems chromium driver instead of the downloaded one:
# chromium which
/snap/bin/chromium
driver = webdriver.Chrome('/snap/bin/chromium.chromedriver',
options=chrome_options)
And for the downloaded webdriver looks like it needs the remote debug port --remote-debugging-port=9222 to be set, as in one of the answers (by Soheil Pourbafrani):
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--remote-debugging-port=9222")
driver = webdriver.Chrome('<path_to>/chromedriver', options=chrome_options)
Date 9/16/2021
Everything works fine running chrome with selenium locally with python inside the docker hosted ubuntu container. When attempting to run from Jenkins the error above is returned WebDriverException: unknown error: DevToolsActivePort
Environment:
-Ubuntu21.04 inside a docker container with RDP access.
-chromedriver for chrome version: 93
Solution:
Inside the python file that starts the browser I had to set the DISPLAY environment variable using the following lines:
import os
os.environ['DISPLAY'] = ':10.0'
#DISPLAY_VAR = os.environ.get('DISPLAY')
#print("DISPLAY_VAR:", DISPLAY_VAR)
In my case, I was trying to create a runnable jar on Windows OS with chrome browser and want to run the same on headless mode in unix box with CentOs on it. And I was pointing my binary to a driver that I have downloaded and packaged with my suite. For me, this issue continue to occur irrespective of adding the below:
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
System.setProperty("webdriver.chrome.args", "--disable-logging");
System.setProperty("webdriver.chrome.silentOutput", "true");
options.setBinary("/pointing/downloaded/driver/path/in/automationsuite");
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("window-size=1024,768"); // Bypass OS security model
options.addArguments("--log-level=3"); // set log level
options.addArguments("--silent");//
options.setCapability("chrome.verbose", false); //disable logging
driver = new ChromeDriver(options);
Solution that I've tried and worked for me is, download the chrome and its tools on the host VM/Unix box, install and point the binary to this in the automation suite and bingo! It works :)
Download command:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
Install command:
sudo yum install -y ./google-chrome-stable_current_*.rpm
Update suite with below binary path of google-chrome:
options.setBinary("/opt/google/chrome/google-chrome");
And.. it works!
I also faced this issue while integrating with jenkins server, I was used the root user for jenkin job, the issue was fixed when I changed the user to other user. I am not sure why this error occurs for the root user.
Google Chrome Version 71.0
ChromeDriver Version 2.45
CentOS7 Version 1.153
I run selenium tests with Jenkins running on an Ubuntu 18 LTS linux. I had this error until I added the argument 'headless' like this (and some other arguments):
ChromeOptions options = new ChromeOptions();
options.addArguments("headless"); // headless -> no browser window. needed for jenkins
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model
ChromeDriver driver = new ChromeDriver(options);
driver.get("www.google.com");
Had the same issue. I am running the selenium script on Google cloud VM.
options.addArguments("--headless");
The above line resolved my issue. I removed the other optional arguments. I think the rest lines of code mentioned in other answers did not have any effect on resolving the issue on the cloud VM.
in my case, when i changed the google-chrome and chromedriver version, the error was fixed :)
#google-chrome version
[root#localhost ~]# /usr/bin/google-chrome --version
Google Chrome 83.0.4103.106
#chromedriver version
[root#localhost ~]# /usr/local/bin/chromedriver -v
ChromeDriver 83.0.4103.14 (be04594a2b8411758b860104bc0a1033417178be-refs/branch-heads/4103#{#119})
ps: selenium verison was 3.9.1
No solution worked for my. But here is a workaround:
maxcounter=5
for counter in range(maxcounter):
try:
driver = webdriver.Chrome(chrome_options=options,
service_log_path=logfile,
service_args=["--verbose", "--log-path=%s" % logfile])
break
except WebDriverException as e:
print("RETRYING INITIALIZATION OF WEBDRIVER! Error: %s" % str(e))
time.sleep(10)
if counter==maxcounter-1:
raise WebDriverException("Maximum number of selenium-firefox-webdriver-retries exceeded.")
It seems there are many possible causes for this error. In our case, the error happened because we had the following two lines in code:
System.setProperty("webdriver.chrome.driver", chromeDriverPath);
chromeOptions.setBinary(chromeDriverPath);
It's solved by removing the second line.
I ran into same issue, i am using UBUNTU, PYTHON and OPERA browser. in my case the problem was originated because i had an outdated version of operadriver.
Solution:
1. Make sure you install latest opera browser version ( do not use opera beta or opera developer), for that go to the official opera site and download from there the latest opera_stable version.
Install latest opera driver (if you already have an opera driver install, you have to remove it first use sudo rm ...)
wget https://github.com/operasoftware/operachromiumdriver/releases/download/v.80.0.3987.100/operadriver_linux64.zip
unzip operadriver_linux64.zip
sudo mv operadriver /usr/bin/operadriver
sudo chown root:root /usr/bin/operadriver
sudo chmod +x /usr/bin/operadriver
in my case latest was 80.0.3987 as you can see
Additionally i also installed chromedriver (but since i did it before testing, i do not know of this is needed) in order to install chromedriver, follow the steps on previous step :v
Enjoy and thank me!
Sample selenium code
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Opera()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.quit()
I came across the same problem, in my case there are two different common user userA and userB in Linux system.
userA first run the selinium programe which start chrome browswer with ChromeDriver successfully, when it came to userB, the DevToolsActivePort file doesn't exist error occur.
I tried the --remote-debugging-port=9222 option, but it lead to a new exception:
selenium.common.exceptions.WebDriverException: Message: chrome not reachable
The I ran google-chome directory and see the following error:
mkdir /tmp/Crashpad/new: Permission denied (13)
The I search the problem and got this:
https://johncylee.github.io/2022/05/14/chrome-headless-%E6%A8%A1%E5%BC%8F%E4%B8%8B-devtoolsactiveport-file-doesn-t-exist-%E5%95%8F%E9%A1%8C/
chrome_options.add_argument(f"--crash-dumps-dir={os.path.expanduser('~/tmp/Crashpad')}")
Thanks to #johncylee.
I'm getting the chrome didn't shut down correctly error message when I reopen a chrome browser in my selenium framework.
In the framework I'm opening the browser instance at the beginning for each of my test case using the below code
if (browserType.equalsIgnoreCase("Chrome")) {
try {
System.setProperty("webdriver.chrome.driver", curProj+"\\drivers\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
options.addArguments("disable-infobars");
//options.addArguments("user-data-dir=C:/Users/xw20/AppData/Local/Google/Chrome/User Data");
options.addArguments(chromeProfile);
webdriver = new ChromeDriver(options);
logger.info("getWebDriver - Setting webdriver.chrome.driver system property as: " + System.getProperty("webdriver.chrome.driver"));
}
catch(IllegalStateException e) {
logger.error("The path to the driver executable must be set by the webdriver.chrome.driver system property. ",e.fillInStackTrace());
throw new IllegalStateException("The path to the driver executable must be set by the webdriver.chrome.driver system property.");
}
and closing at the end using the below code
driver.close();
driver.quit();
But when I open a browser for the second test case I'm getting "chrome didn't shut down correctly" popup message.
I tried updating the below in the Preferences file of chrome profile but no luck
exit_type:Crashed
exited_cleanly:true
Configuration :
Chrome Version: Version 64.0.3282.186 (Official Build) (32-bit)
Selenium Version: 3.11.0
As per your code it would be tough to analyze the reason behind the error chrome didn't shut down correctly without knowing your framework structure. Perhaps a more details about how code block was invoked (i.e. main() or TestNG) would have helped us.
Having said that there still seems some more factors to look at as follows :
If you are using an existing Chrome Profile through user-data-dir ideally you should avoid the switches setExperimentalOption and addArguments for customization as those should be set within the respective Chrome Profile.
As you are using an existing Chrome Profile through user-data-dir as per the documentation ChromeDriver - WebDriver for Chrome the path should point the profile directory as follows :
options.add_argument("user-data-dir=C:/Users/xw20/AppData/Local/Google/Chrome/User Data/Profile 2")
Here you can find a detailed discussion at How to open a Chrome Profile through Python
Avoid using driver.close(); and always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
Here you can find a detailed discussion at PhantomJS web driver stays in memory
Upgrade JDK to recent levels JDK 8u162.
Upgrade Selenium to current levels Version 3.11.0.
Upgrade ChromeDriver to current ChromeDriver v2.37 level.
Upgrade Chrome version to current Chrome v65.x levels.
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
Execute your #Test.
Did you set exit_type:Normal, I'm currently doing that before the test start, and or after the test ends and it Works.
on C#
public static void FixChromeSingleProfile(string dataDir)
{
FileStream fs = new FileStream(dataDir, FileMode.OpenOrCreate);
StreamReader sr = new StreamReader(fs);
string json = sr.ReadToEnd();
sr.Close();
fs.Close();
dynamic jsonDe = JsonConvert.DeserializeObject(json);
if (jsonDe.profile.exit_type != "Normal")
{
jsonDe.profile.exit_type = "Normal";
string r = JsonConvert.SerializeObject(jsonDe);
StreamWriter sw = new StreamWriter(dataDir, false);
sw.Write(r);
sw.Close();
}
}
This solution is in Python and works 100% but you should be able to implement this in Java as well. I just call the close_windows function every time I am finished using Selenium.
def close_windows():
windows = driver.window_handles
for w in windows:
driver.switch_to.window(w)
driver.close()
driver.quit()
close_windows()
Im new to Mac OSX. Downloaded my Robotframework(Selenium & Java) project from git and tried to execute the code locally wherein I received the below error.
Suite setup failed:
IllegalStateException: The driver is not executable: /Users/roja/Documents/GitHub/testautomation/chromedrivers/chromedriver_osx
To rectify this issue, I followed the below but it didnt work.
Upgraded the selenium-java and standalone version from 2.53.1 to 3.4.0.
Driver path specified to Users/roja/automation
Chromedriver upgraded from 2.31 to 2.33
And the same driver version updated even in the path specified in the exception above.
Also Im unsure why the path is defaulted to /Users/roja/Documents/GitHub/testautomation/chromedrivers/chromedriver_osx. My git projects are saved in the path usr/local/git/testautomation and chromedriver also saved in the same. please clarify and provide me a solution.
Below code written for launching the browser,
public void LaunchBrowser() throws InterruptedException {
System.setProperty("Webdriver.chrome.driver", "/Users/roja/Automation/chromedriver_osx");
driver = new ChromeDriver();
driver.manage().window().maximize();
}
Quick installation of the latest ChromeDriver
To install the latest version of ChromeDriver:
Mac users with Homebrew:
brew tap homebrew/cask && brew cask install chromedriver
Original answered Nov 15 '17 at 12:04
The error IllegalStateException: The driver is not executable: /Users/roja/Documents/GitHub/testautomation/chromedrivers/chromedriver_osx says it all. You have to make exactly 4 changes as follows :
Change Webdriver.chrome.driver as :
webdriver.chrome.driver
Change /Users/roja/Automation/chromedriver_osx as we need to include the name of the webdriver binary i.e. chromedriver as a value :
/Users/roja/Automation/chromedriver_osx/chromedriver
Change driver = new ChromeDriver(); as :
WebDriver driver = new ChromeDriver();
Remove unwanted throws InterruptedException to keep your code short and simple.
FYI I had to do the solution proposed by varunrao321: Navigate to the folder containing chromedriver and run chmod +x chromedriver
I tried giving full permission to the chromedriver and it works fine.
chmod +x chromedriver
or
chmod 777 chromedriver
Another solution that worked for me.
Navigate to the folder containing chromedriver and run
"chmod +x chromedriver"
Worked for me as well:
Step 1: Open terminal
Step 2: Navigate to the path folder containing chromedriver
Step 3: Run chmod +x chromedriver
#debanjan already explain good expalaination to you, I am just giving you correct code:
public void LaunchBrowser() throws InterruptedException {
System.setProperty("webdriver.chrome.driver", "/Users/roja/Automation/chromedriver_osx/chromedriver");
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
}
It may be due to the permission access. Download the chrome driver using http://chromedriver.chromium.org/downloads and then give path.
Example:
System.setProperty("webdriver.chrome.driver","/Users/xyz/Downloads/chromedriver");
The way I solved this problem was by importing the chromedriver with right click>Import instead of dragging it to the folder.
I don't know exactly why, but it worked.
For me, it was the last driver that was not working with the chrome version installed on my macOS mojave. I was forced to install last version of google chrome, then it worked.
You may install chromedriver by brew
brew cask install chromedriver
After that, as DebanjanB said, replace your
System.setProperty("Webdriver.chrome.driver","/Users/roja/Automation/chromedriver_osx");
with
System.setProperty("webdriver.chrome.driver", "/usr/local/bin/chromedriver");
It works for me.
One More Solution :
Visit : https://sites.google.com/a/chromium.org/chromedriver/downloads
enter image description here
Under "Current Releases" section, Click on Chrome driver link which is updated in your system.
Automatically it will redirect to "https://chromedriver.storage.googleapis.com/index.html?path="
enter image description here
Click on link for mac and unzip the folder.
Now paste chromedriver.exe file into your project.
And provide below mentioned code-
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class SetChromeDriver {
public static void main(String[] args) {
// TODO Auto-generated method stub
System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir") + "/chromedriver");
WebDriver driver = new ChromeDriver();
driver.get("https://www.google.com/");
driver.quit();
}
}
Run this command in the folder where chromedriver is present: chmod +x chromedriver
I am using selenium 3.2.0 standalone, chrome latest version and chrome driver latest version which is giving not able to connect exemption on running.
Issue is with chrome driver please help
org.openqa.selenium.SessionNotCreatedException:
my code look like this:
System.setProperty("webdriver.chrome.driver","E:/WorkSpace/Econsys_Auto/Jarfiles/chromedriver.exe");
System.setProperty("webdriver.chrome.driver","E:/WorkSpace/Econsys_Auto/Jarfiles/chromedriver.exe");
DesiredCapabilities capabilities=DesiredCapabilities.chrome();
capabilities.setBrowserName("chrome");
capabilities.setPlatform(Platform.XP);
System.out.println("*******");
driver = new RemoteWebDriver(new URL(nodeUrl), capabilities);
driver.get(baseUrl);
Got selenium 3.2.0 with chromedriver 2.28, but I got Win10.
Try this code:
System.setProperty("webdriver.chrome.driver", "chromedriver.exe");//use your path
try{
driver = new ChromeDriver();
}
catch (Exception e) {
System.out.println(e);
}
I would suggest that you please try again using Selenium 3.3.0 (which is released just now)
There was an issue in Selenium (versions previous to 3.3.0) which was preventing the actual reason for the new session failure from being relayed to the test. That explains why you are not able to identify the root cause.
This now stands fixed in Selenium 3.3.0 as part of this commit
Now coming back to the possible reasons why your tests are not spawning a chrome browser.
I notice that you are using
System.setProperty("webdriver.chrome.driver","E:/WorkSpace/Econsys_Auto/Jarfiles/chromedriver.exe");
in your test code.
This sets up the JVM argument webdriver.chrome.driver ONLY for the current JVM. The Grid and the node are running in a different JVM (remember you spawned them using java -jar command ?).
I would instead recommend that you add "E:/WorkSpace/Econsys_Auto/Jarfiles/" to your PATH variable. This is a one time exercise you would be doing on a "per machine" basis and this will ensure that Selenium finds the chromedriver binary's location (I think that's why your tests are failing and you should be able to confirm this, if you looked at the node's console logs)
