how to fix "SessionNotCreatedException: session not created: DevToolsActivePort file doesn't exist"

Question

Dear MS,
I'm following this link to try to use selenium and python to usewebdriver for edge

https://learn.microsoft.com/en-us/microsoft-edge/webdriver-chromium/?tabs=python

And I followed the first example from the site

from selenium import webdriver from selenium.webdriver.common.by import By import time driver = webdriver.Edge() driver.get('https://bing.com') element = driver.find_element(By.ID, 'sb_form_q') element.send_keys('WebDriver') element.submit() time.sleep(5) driver.quit()

However, I got the following error:

File ~\AppData\Local\anaconda3\envs\snowpy\Lib\site-packages\selenium\webdriver\remote\errorhandler.py:229 in check_response

raise exception_class(message, screen, stacktrace)

SessionNotCreatedException: session not created: DevToolsActivePort file doesn't exist

How to fix it?

Thanks.

Hi @Zhao, Tina SIEP-PTX/D/S

Which version of Edge and Edge WebDriver do you use? Which version of Selenium do you use?

You could try the following possible solutions:

1. Make sure you are using the latest version of Microsoft Edge and Edge driver.
2. Make sure you are using Selenium 4.
3. Kill all the processes of Microsoft Edge in Task Manager before you run the code and test again.
4. Add options like below:

      edge_options = webdriver.EdgeOptions()
      edge_options.add_argument("no-sandbox")
      edge_options.add_argument("disable-dev-shm-usage")
      driver = webdriver.Edge(options = edge_options)
