The process started from chrome location C:\..\Chrome\Application\chrome.exe is no longer running, so ChromeDriver is assuming that Chrome has crashed

Question

Chrome version: 68.0.3440.106
Chrome webdriver version: ChromeDriver 2.41.578737
Python Version : Python 3.5.2

I write this code in python:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys


o = webdriver.ChromeOptions()
o.add_argument("disable-extensions");
o.add_argument("--start-maximized");
driver = webdriver.Chrome(executable_path=r"chromedriver.exe",options=o)
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.close()

after few seconds chrome opened with this error:

and nothing happend till i close chrome and get this exception:

    Traceback (most recent call last):
  File ".../game.py", line 8, in <module>
    driver = webdriver.Chrome(executable_path=r"chromedriver.exe",options=o)

Solution 1

Today I was the same trouble and I fixed using:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys


o = webdriver.ChromeOptions()
o.add_argument("disable-extensions")
o.add_argument("--start-maximized")
o.binary_location = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" ## This line define path of browser. In this case, Google Chrome
driver = webdriver.Chrome(executable_path=r"chromedriver.exe",options=o)
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.close()

Solution 2

I recently had this issue using TeamCity, which was caused by chrome (and chromedriver) not shutting down after executing my script. inserting "taskkill /f /im chrome.exe" and "taskkill /f /im chromedriver.exe" fixed this issue.

Solution 3

use correct argument for disabling extension:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
o = Options()
#o.add_argument("--disable-extensions"); #here
o.add_experimental_option("useAutomationExtension", false); #you can try this as well
o.add_argument("--start-maximized");
driver = webdriver.Chrome(executable_path=r"chromedriver.exe",chrome_options=o)
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.close()

see this post: Selenium Crashing: Chrome automation extension has crashed

[assaf.b]

saw, didn't helped.

[theGuy]

you are not using correct argument, use: o.add_argument("--disable-extensions");

[theGuy]

you can try one more option: o.setExperimentalOption("useAutomationExtension", false); This capability will help to not load Chrome Automation extension. I have updated my answer.

[assaf.b]

still didn't work, in python is o.add_experimental_option("useAutomationExtension", False)

[theGuy]

my bad, you are right. I mixed up python and java. Btw are you still getting same error?

[assaf.b]

The chrome was opened but after I close the window (after alot of time without any response but the error massage) I get this exception, your answer doesn't help me at all, but thanks for the try.

[Oliver.R]

Can you explain which part you changed to fix this issue?

Oliver, add this line: o.binary_location = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" ## This line define path of browser. In this case, Google Chrome
