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:

Answer 1

This error message...

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited normally
  (unknown error: unable to discover open pages)
  (The process started from chrome location C:\Program Files (x86)\Google\Chrome\Application\chrome.exe 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 seems that the chrome binary i.e. chrome.exe and the associated files are no more available/accessible from the default location of:

C:\Program Files (x86)\Google\Chrome\Application\

The possible reasons are:

• Chrome previously installed at the default location got corrupted/deleted.

• If you have installed Chrome Browser at a non-standard location you need to do:

  opt = webdriver.ChromeOptions()
  opt.binary_location("/path/to/other/chrome/binary");
  

• Here you find a detailed discussion on Cannot find Chrome binary with Selenium in Python for older versions of Google Chrome

Additional considerations

• Chrome and ChromeDriver are present in the desired location.
• Chrome and ChromeDriver are having executable permission for non-root (non-administrator) users.
• Upgrade Selenium to current levels Version 3.14.0.
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• (WindowsOS only) Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
• (LinuxOS only) Free Up and Release the Unused/Cached Memory in Ubuntu/Linux Mint 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.
• Take a System Reboot.
• Execute your @Test as a non-root user.
• Run the selenium server with webdriver-manager start from the machine with the desktop (don't use a remote session to start the selenium server).

Answer 2

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()

Answer 3

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()
