[FEATURE] list uninstall command for optional packages #20

Closed ghost closed 3 years ago

ghost commented 3 years ago

Would you please list the command to uninstall Optional packages.

I have run into a conflict and can't install one of the optional packages. The advice is to downgrade or uninstall everything. 

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

I ran the following command and now I cannot reinstall webchanges and optional packages: pip freeze | xargs pip uninstall -y then:

pip install webchanges
pip install --upgrade webchanges[use_browser]
pip install --upgrade webchanges[bs4]
pip install --upgrade webchanges[beautify]

that last one is where things went haywire...
