Installing webdriver_manager

Hi! I have a Flask app that needs the library webdriver_manager. That app runs in a virtual environment, and I have managed to successfully import other libraries that I installed in this virtual env, but not webdriver_manager, which I can install on the virtual env, but my script still gives me the ModuleNotFoundError. Is there any issue with this library in particular, in PythonAnywhere? And yes, if needed, you can look into my account.

can you give the full error stacktrace? also, if you are using a browser to scrape stuff, check out this.
