selenium.common.exceptions.WebDriverException: Message: unknown error: Failed to create a Chrome process error with ChromeDriver Chrome Selenium

问题

I am trying to code basic python-Google Chrome interactions with webdriver but I constantly get the same error while trying to launch a link on my browser.

Here is my code:

from selenium import webdriver
import os

class Instagrambot:
    def __init__(self, username, password):
        self.username = username
        self.password = password

        self.driver = webdriver.Chrome('./chromedriver.exe')


if __name__ == '__main__':
    ig_bot = Instagrambot('temp_username', 'temp_password')

I have the chromedriver in the current directory, and I am using the correct version of the chromedriver (79.0.3945.36) for my browser (Chrome 79.0.3945.88) . The full error I am getting is:

Traceback (most recent call last):
  File "c:/Users/Arthur/Documents/instabot/bot.py", line 16, in <module>
    ig_bot = Instagrambot('temp_username', 'temp_password')

  File "C:\Users\Arthur\AppData\Local\Programs\Python\Python37-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 252, in start_session response = self.execute(Command.NEW_SESSION, parameters)
  File "C:\Users\Arthur\AppData\Local\Programs\Python\Python37-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "C:\Users\Arthur\AppData\Local\Programs\Python\Python37-32\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response 
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: Failed to create a Chrome process.

I have already tried:

Writing the full executable path towards chromedriver.exe (same folder of bot.py)

Overriding the Chrome binary location as suggested in this answer: https://stackoverflow.com/a/53078276/11206079

If anyone can help me or give any insight about how to fix it I would be really glad!

回答1:

This error message...

selenium.common.exceptions.WebDriverException: Message: unknown error: Failed to create a Chrome process.

...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session.

I don't see any such issue in your code block. However, a bit more details about your Test Environment with respect to version of the binaries and user type you are using would have helped us to debug the issue in a better way. However most possibly you are executing your test as an administrator

Solution

Execute your test as a non-administrator / non-root user.

Additional considerations

Ensure that:

Selenium is upgraded to current levels Version 3.141.59.
ChromeDriver is updated to current ChromeDriver v79.0.3945.36 level.
Chrome is updated to current Chrome Version 79.0 level. (as per ChromeDriver v79.0 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
