@xahlee Never use sudo pip or sudo easy_install . I don't know why it's in all the manuals. Always use: pip install --user ← that USER is super important. You should never let pip or cargo or any other language manager ever touch your system packages. gem also has a gem install --user which you should use to. You can always wipe/reset your home directory. The system is much more difficult.
