Recently I switched computers and since then I can't launch chrome with selenium. I've also tried Firefox but the browser instance just doesn't launch.
from selenium import webdriver
d = webdriver.Chrome('/home/PycharmProjects/chromedriver')
d.get('https://www.google.nl/')
i get the following error:
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /opt/google/chrome/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
(Driver info: chromedriver=2.43.600233, platform=Linux 4.15.0-38-generic x86_64)
i have the latest chrome version and chromedriver installed
EDIT:
After trying #b0sss solution i am getting the following error.
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed

Try to download HERE and use this latest chrome driver version:
https://sites.google.com/chromium.org/driver/
Try this:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
d = webdriver.Chrome('/home/<user>/chromedriver',chrome_options=chrome_options)
d.get('https://www.google.nl/')
This error message...
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /opt/google/chrome/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Your main issue is the Chrome browser is not installed at the default location within your system.
The server i.e. ChromeDriver expects you to have Chrome installed in the default location for each system as per the image below:
1For Linux systems, the ChromeDriver expects /usr/bin/google-chrome to be a symlink to the actual Chrome binary.
Solution
In case you are using a Chrome executable in a non-standard location you have to override the Chrome binary location as follows:
Python Solution:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.binary_location = "C:\\path\\to\\chrome.exe" #chrome binary location specified here
options.add_argument("--start-maximized") #open Browser in maximized mode
options.add_argument("--no-sandbox") #bypass OS security model
options.add_argument("--disable-dev-shm-usage") #overcome limited resource problems
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')
Java Solution:
System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
ChromeOptions opt = new ChromeOptions();
opt.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe"); //chrome binary location specified here
options.addArguments("start-maximized");
options.setExperimentalOption("excludeSwitches", Collections.singletonList("enable-automation"));
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(opt);
driver.get("https://www.google.com/");
hope this helps someone. this worked for me on Ubuntu 18.10
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.add_argument('--no-sandbox')
driver = webdriver.Chrome('/usr/lib/chromium-browser/chromedriver', options=chrome_options)
driver.get('http://www.google.com')
print('test')
driver.close()
I encountered the exact problem running on docker container (in build environment). After ssh into the container, I tried running the test manually and still encountered
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /usr/bin/google-chrome-stable is
no longer running, so ChromeDriver is assuming that Chrome has crashed.)
When I tried running chrome locally /usr/bin/google-chrome-stable, error message
Running as root without --no-sandbox is not supported
I checked my ChromeOptions and it was missing --no-sandbox, which is why it couldn't spawn chrome.
capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
chromeOptions: { args: %w(headless --no-sandbox disable-gpu window-size=1920,1080) }
)
I had a similar issue, and discovered that option arguments must be in a certain order. I am only aware of the two arguments that were required to get this working on my Ubuntu 18 machine. This sample code worked on my end:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
d = webdriver.Chrome(executable_path=r'/home/PycharmProjects/chromedriver', chrome_options=options)
d.get('https://www.google.nl/')
For RobotFramework
I solved it! using --no-sandbox
${chrome_options}= Evaluate sys.modules['selenium.webdriver'].ChromeOptions() sys, selenium.webdriver
Call Method ${chrome_options} add_argument test-type
Call Method ${chrome_options} add_argument --disable-extensions
Call Method ${chrome_options} add_argument --headless
Call Method ${chrome_options} add_argument --disable-gpu
Call Method ${chrome_options} add_argument --no-sandbox
Create Webdriver Chrome chrome_options=${chrome_options}
Instead of
Open Browser about:blank headlesschrome
Open Browser about:blank chrome
Assuming that you already downloaded chromeDriver, this error is also occurs when already multiple chrome tabs are open.
If you close all tabs and run again, the error should clear up.
in my case, the error was with www-data user but not with normal user on development. The error was a problem to initialize an x display for this user. So, the problem was resolved running my selenium test without opening a browser window, headless:
opts.set_headless(True)
A simple solution that no one else has said but worked for me was not running without sudo or not as root.
The solutions that every body provide here is good for Clear the face of the issue but
All you need to solve this problem is that You have to run The App on non-root user
on linux.
According to this post
https://github.com/paralelo14/google_explorer/issues/2#issuecomment-246476321
I had the same problem but it was solved just by reinstalling chrome again with the commands below:
$ wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
$ sudo apt install ./google-chrome-stable_current_amd64.deb
This error has been happening randomly during my test runs over the last six months (still happens with Chrome 76 and Chromedriver 76) and only on Linux. On average one of every few hundred tests would fail, then the next test would run fine.
Unable to resolve the issue, in Python I wrapped the driver = webdriver.Chrome() in a try..except block in setUp() in my test case class that all my tests are derived from. If it hits the Webdriver exception it waits ten seconds and tries again.
It solved the issue I was having; not elegantly but it works.
from selenium import webdriver
from selenium.common.exceptions import WebDriverException
try:
self.driver = webdriver.Chrome(chrome_options=chrome_options, desired_capabilities=capabilities)
except WebDriverException as e:
print("\nChrome crashed on launch:")
print(e)
print("Trying again in 10 seconds..")
sleep(10)
self.driver = webdriver.Chrome(chrome_options=chrome_options, desired_capabilities=capabilities)
print("Success!\n")
except Exception as e:
raise Exception(e)
I came across this error on linux environment. If not using headless then you will need
from sys import platform
if platform != 'win32':
from pyvirtualdisplay import Display
display = Display(visible=0, size=(800, 600))
display.start()
Faced with this issue trying to run/debug Python Selenium script inside WSL2 using Pycharm debugger.
First solution was to use --headless mode, but I prefer to have Chrome GUI during the debug process.
In the system terminal outside Pycharm debugger Chrome GUI worked nice with DISPLAY env variable set this way (followed guide here):
export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0
Unfortunately ~/.bashrc is not running in Pycharm during the debug, export is not working.
The way I've got Chrome GUI worked from Pycharm debugger: run echo $DISPLAY in WSL2, paste ip (you've got something similar to this) 172.18.144.1:0 into Pycharm Debug Configuration > Environment Variables:
Just do not run the script as the root user (in my case).
i had same problem. I was run it on terminal with "sudo geany", you should run it without "sudo" just type on terminal "geany" and it is solved for me.
i faced the same problem but i solved it by moving the chromedriver to this path
'/opt/google/chrome/'
and this code works correctly
from selenium.webdriver import Chrome
driver = Chrome('/opt/google/chrome/chromedrive')
driver.get('https://google.com')
In my case, chrome was broken. following two lines fixed the issue,
apt -y update; apt -y upgrade; apt -y dist-upgrade
apt --fix-broken install
Fixed it buy killing all the chrome processeses running in the remote server before running my script.
That may explain why some answers that recommend you run your script as root works.
$ pkill -9 chrome
$ ./my_script.py
Maybe when you where developing in local, you used options.headless=False in order to see what is the browser doing but you forgot to change it to True in the vm.
For me, the root issue was that the google-chrome/chromedriver version were not compatible with the Selenium version.
Seleniumn and Chrome were working fine until a few days ago and I started getting this missing DevToolsActivePort issue. After trying all sorts of solutions on this thread, it finally occurred to me that the Chrome version might not be compatible with the Selenium version.
Versions at the time of the initial error:
# Below combo does NOT work
Python 3.7.3
selenium==3.141.0
Google Chrome 110.0.5481.77
ChromeDriver 110.0.5481.77
I then downgraded Chrome and ChromeDriver to 109.0.5414.74 but still faced the same error. I checked the versions on a different machine and saw that this combo worked:
# Below combo works
Python 3.7.6
selenium==3.141.0
Google Chrome 80.0.3987.100
ChromeDriver 80.0.3987.16
However, I wasn't able to find a download for Google Chrome V80. This comment had a download to V97 so that's the version I went with. There might be higher versions of Google Chrome that do work but after spending so many days fixing this, I was eager to move onto something else.
sudo apt-get purge google-chrome-stable
sudo wget http://dl.google.com/linux/chrome/deb/pool/main/g/google-chrome-stable/google-chrome-stable_97.0.4692.71-1_amd64.deb && \
sudo dpkg -i google-chrome-stable_97.0.4692.71-1_amd64.deb && \
sudo apt-mark hold google-chrome-stable
wget https://chromedriver.storage.googleapis.com/97.0.4692.71/chromedriver_linux64.zip
sudo unzip chromedriver_linux64.zip chromedriver -d /usr/local/bin
After that, my Selenium calls were able to work again. The final version combo:
# Below combo works
Python 3.7.3
selenium==3.141.0
ChromeDriver 97.0.4692.71
Google Chrome 97.0.4692.71
Make sure that both the chromedriver and google-chrome executable have execute permissions
sudo chmod -x "/usr/bin/chromedriver"
sudo chmod -x "/usr/bin/google-chrome"
I'm running Selenium tests for Chrome through Jenkins pipeline on CentOs machine. When ran, it gives following error -
org.openqa.selenium.WebDriverException: unknown error: Chrome failed to start: exited abnormally
[testng] (unknown error: DevToolsActivePort file doesn't exist)
[testng] (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
However if I run same tests with same command(which is used through Jenkins pipeline) from that machine locally, it succeeds.
For the same, I went through link1, link2, link3 and other answers. From those answers, only following helped -
chrome_options.add_argument('--headless')
But this run tests with chrome in headless mode which is not my intention.
In my case, having matching Chrome browser and chromedriver version did not help, also Chrome has executable permission for all.
Note: I've my CentOs machine display enabled
Could you please help to understand what is causing this failure? Also please help with what code and/or machine level changes I've to make for its success.
EDIT:
In case, this helps to get more info.
ls | grep 'chrome' under /usr/bin gave following result -
lrwxrwxrwx 1 root root 31 Jan 20 12:29 google-chrome -> /etc/alternatives/google-chrome
lrwxrwxrwx 1 root root 32 Jan 20 12:29 google-chrome-stable -> /opt/google/chrome/google-chrome
Do you run chromedriver locally on a linux machine? What version of CentOS are you using? If you haven't already you need to install the correct chromedriver for linux. As far as I know if you want to run via Jenkins you have to run in headless mode. But I may be wrong. Below is another post that can help:

Below are my own settings for chrome options:

After update of chromedriver to version 2.46 my tasts fail to initialize.
I got message like this:

Command duration or timeout: 1.58 seconds
Build info: version: '2.53.1'
It is clearly saying that my browser version is not valid. But I am using Chrome 72.0.3626.119 so it is between 71 and 75.
Selenium version is 2.53.1.
And I am running test through console command with the help of testNG.
Any idea? Every ideas that I found was about changing selenium version but I cant do it.
For me to resolve this problem :
On Windows
cd C:\Users\[myname]\AppData\Roaming\npm\node_modules\protractor
npm i webdriver-manager#latest
webdriver-manager update
webdriver-manager start &
On Cent-OS (I used Cent-OS 7.4.* and it worked fine.)
cd /usr/lib/node_modules/protractor/
sudo npm i webdriver-manager#latest
sudo webdriver-manager update
sudo webdriver-manager start &
I hope this helps you in any way.

Failed to invoke configuration method com.personal.CustomTest.initTests not created: Chrome version must be between 71 and 75
...implies that the ChromeDriver v2.46 is not compatible with the Chrome Browser version which is being accessed by your program/webdriver.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
You are using chromedriver=2.46
Release Notes of chromedriver=2.46 clearly mentions the following :
Supports Chrome v71-73
Though you mentioned you are using Chrome 72.0.3626.119 possibly there are multiple instances of Chrome Browser installed within your system and your program by default is accessing the Chrome Browser whose version is not between v71.x and v75.x
You are using chrome=67.0
Release Notes of ChromeDriver v2.38 clearly mentions the following :
Supports Chrome v65-67
Solution
Keep JDK upgraded to recent levels JDK 8u201.
Uninstall all the instances of Chrome Browser (you can opt to use Revo Uninstaller).
Upgrade ChromeDriver to current ChromeDriver v2.46 level.
Keep Chrome version between Chrome v71-73 levels. (as per ChromeDriver v2.46 release notes)
For me, I had to update my chrome driver in my project to match the version of Chrome on my local machine.
yarn add chromedriver#76.0.0 -D
https://www.npmjs.com/package/chromedriver
In my case I was getting the same error after my chrome was updated to version 76. Which was happening when chimp tries to use chromedriver to execute the selenium test.

For me it didn't work when I updated the chrome driver by npm (both globally and locally) and then I followed these steps to resolve the issue, which might give some idea on where to check in this kind a issue:
Because exception was thrown in node_modules\chimp\dist\lib\utils\fiberize.js i navigated to that file and found one level above this file node_modules\chimp\dist\lib\chromedriver.js which has the code to start chromedriver.
I added a console.log to chromedriverPath which can be seen below and re-executed the tests to get the chromedriver path in console logs.
Chromedriver.prototype.start = function(callback) {
var self = this;
var port = self.options.port;
if (this.child) {
callback();
return;
}
var chromedriverPath = chromedriver.path;
//this was added my me the see that chrome drive path
console.log("[chimp] " + chromedriverPath);
if (fs.existsSync(chromedriverPath)) {
this.child = processHelper.start(
{
bin: chromedriverPath,
prefix: "chromedriver",
args: ["--port=" + port, "--url-base=wd/hub"],
waitForMessage: /Starting ChromeDriver/,
errorMessage: /Error/
},
callback
);
} else {
callback("[chimp][chromedriver] Chromedriver executable not found.");
}
};
When i got the path of the chromedriver which is used to execute the tests, i just navigated to that folder and replaced chromedriver executable with the most recent version.
I hope this helps.
Try this: Download the compatible ChromeDriver.exe file for the updated version of Chrome browser and replace it. It works for me.
Recently I switched computers and since then I can't launch chrome with selenium. I've also tried Firefox but the browser instance just doesn't launch.

I came across this error on linux environment. If not using headless then you will need
from sys import platform
if platform != 'win32':
from pyvirtualdisplay import Display
display = Display(visible=0, size=(800, 600))
display.start()
Faced with this issue trying to run/debug Python Selenium script inside WSL2 using Pycharm debugger.
First solution was to use --headless mode, but I prefer to have Chrome GUI during the debug process.
In the system terminal outside Pycharm debugger Chrome GUI worked nice with DISPLAY env variable set this way (followed guide here):
export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0
Unfortunately ~/.bashrc is not running in Pycharm during the debug, export is not working.
The way I've got Chrome GUI worked from Pycharm debugger: run echo $DISPLAY in WSL2, paste ip (you've got something similar to this) 172.18.144.1:0 into Pycharm Debug Configuration > Environment Variables:
Just do not run the script as the root user (in my case).
i had same problem. I was run it on terminal with "sudo geany", you should run it without "sudo" just type on terminal "geany" and it is solved for me.
i faced the same problem but i solved it by moving the chromedriver to this path
'/opt/google/chrome/'
and this code works correctly
from selenium.webdriver import Chrome
driver = Chrome('/opt/google/chrome/chromedrive')
driver.get('https://google.com')
In my case, chrome was broken. following two lines fixed the issue,
apt -y update; apt -y upgrade; apt -y dist-upgrade
apt --fix-broken install
Fixed it buy killing all the chrome processeses running in the remote server before running my script.
That may explain why some answers that recommend you run your script as root works.
$ pkill -9 chrome
$ ./my_script.py
Maybe when you where developing in local, you used options.headless=False in order to see what is the browser doing but you forgot to change it to True in the vm.
For me, the root issue was that the google-chrome/chromedriver version were not compatible with the Selenium version.
Seleniumn and Chrome were working fine until a few days ago and I started getting this missing DevToolsActivePort issue. After trying all sorts of solutions on this thread, it finally occurred to me that the Chrome version might not be compatible with the Selenium version.
Versions at the time of the initial error:
# Below combo does NOT work
Python 3.7.3
selenium==3.141.0
Google Chrome 110.0.5481.77
ChromeDriver 110.0.5481.77
I then downgraded Chrome and ChromeDriver to 109.0.5414.74 but still faced the same error. I checked the versions on a different machine and saw that this combo worked:
# Below combo works
Python 3.7.6
selenium==3.141.0
Google Chrome 80.0.3987.100
ChromeDriver 80.0.3987.16
However, I wasn't able to find a download for Google Chrome V80. This comment had a download to V97 so that's the version I went with. There might be higher versions of Google Chrome that do work but after spending so many days fixing this, I was eager to move onto something else.
sudo apt-get purge google-chrome-stable
sudo wget http://dl.google.com/linux/chrome/deb/pool/main/g/google-chrome-stable/google-chrome-stable_97.0.4692.71-1_amd64.deb && \
sudo dpkg -i google-chrome-stable_97.0.4692.71-1_amd64.deb && \
sudo apt-mark hold google-chrome-stable
wget https://chromedriver.storage.googleapis.com/97.0.4692.71/chromedriver_linux64.zip
sudo unzip chromedriver_linux64.zip chromedriver -d /usr/local/bin
After that, my Selenium calls were able to work again. The final version combo:
# Below combo works
Python 3.7.3
selenium==3.141.0
ChromeDriver 97.0.4692.71
Google Chrome 97.0.4692.71
Make sure that both the chromedriver and google-chrome executable have execute permissions
sudo chmod -x "/usr/bin/chromedriver"
sudo chmod -x "/usr/bin/google-chrome"
When I run xampp on fedora this error is showing up on application log
Starting Apache Web Server...
Exit code: 8
Stdout:
apache config test fails, aborting
Stderr:
httpd: Syntax error on line 522 of /opt/lampp/etc/httpd.conf: Syntax error on line 10 of /opt/lampp/etc/extra/httpd-xampp.conf: Cannot load modules/libphp7.so into server: libnsl.so.1: cannot open shared object file: No such file or directory
can anyone tell me how can I solve this?
it seems you're missing libnsl. install it through this command:
sudo dnf install libnsl
In case this doesn't work you can then download it manually:
Visit https://pkgs.org/
In the search box (pkgs.org of course) type libnsl.so.1 and choose the appropriate OS. The version shown might be higher e.g libnsl-2.28-9.fc29.x86_64.rpm, but it doesn't matter, the file needed is also included in this very package.
In the terminal, navigate to the directory where the .rpm was downloaded.
Type the following command to install it:
sudo rpm libnsl-2.XX-X.fc29.x86_64.rpm
Upon completion everything should be working fine.
A quick Google search returns this: https://www.reddit.com/r/Fedora/comments/8hlhlv/xampp_with_fedora_28/
The suggested fix is installing libnsl from this source:
