Is Chromedriver_autoinstaller still working?-CodePudding

I would like to run chromedriver_autoinstaller. I follow example here: https://pypi.org/project/chromedriver-autoinstaller/

from selenium import webdriver
import chromedriver_autoinstaller


chromedriver_autoinstaller.install()  # Check if the current version of chromedriver exists
                                      # and if it doesn't exist, download it automatically,
                                      # then add chromedriver to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")
assert "Python" in driver.title

But I got an error:

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist

What does it mean? Is this package still working?

CodePudding user response：

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.

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.

Execute your test as a regular user.
