How do I remove all packages installed by pip?

I’ve found this snippet as an alternative solution. It’s a more graceful removal of libraries than remaking the virtualenv:

pip freeze | xargs pip uninstall -y

In case you have packages installed via VCS, you need to exclude those lines and remove the packages manually (elevated from the comments below):

pip freeze | grep -v "^-e" | xargs pip uninstall -y

If you have packages installed directly from github/gitlab, those will have @.
Like:

django @ git+https://github.com/django.git@<sha>

You can add cut -d "@" -f1 to get just the package name that is required to uninstall it.

pip freeze | cut -d "@" -f1 | xargs pip uninstall -y
