I'm trying to fix up one of my virtualenvs - I'd like to reset all of the installed libraries back to the ones that match production.
Is there a quick and easy way to do this with 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
