I'm attempting to import WebDriverManager for Chrome, but this is what I get

$ pip install webdriver-manager                                  
Defaulting to user installation because normal site-packages is not writeable           
Requirement already satisfied: webdriver-manager in ./.local/lib/python3.10/site-packages (3.8.1)                                                                               
Requirement already satisfied: requests in /usr/lib/python3/dist-packages (from webdriver-manager) (2.25.1)                                                                     
Requirement already satisfied: python-dotenv in ./.local/lib/python3.10/site-packages (from webdriver-manager) (0.20.0)

I cannot get an instance of Chrome up and running where as I have google-chrome-stable (103.0.5060.114-1) installed.

Possibly there are multiple versions of Python involved. So it would be much safer to invoke pip via the exec module approach, so you are aware about the desired Python executable version.

You can follow the below steps:

  • (optional) Uninstall the previously installed python3 and install a fresh version of python3.

  • Install Selenium

    pip3 install -U selenium

  • Install Webdriver Manager for Python

    pip3 install webdriver-manager

  • So I actually solved it by inputting the following: driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install())) – javery1337 Jul 22 '22 at 20:25
  • In the question you mentioned that the error was in this line only `driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))` – undetected Selenium Jul 22 '22 at 20:32
