Selecting python3.4 interpreter for Django broke pip

I had pip, pip2, and pip3 working before installing PyCharm. I opened the IDE to try it out and took those steps: 

Welcome Screen --> Create New Project --> Django (Interpreter: 3.4.3 at /usr/bin/python3.4) --> Create.

Trying pip3 yields similar results. This just wasn't happening before.

Please advise.
