Pip Install Error: Cannot Import Name 'unpack_url'

I'm using Python 3.4.1 64-bit on a Windows 8.1 machine. Pip has been giving me problems lately, specifically this error: C:\Users\Charlie\Desktop>pip install wxPython_Phoenix-3

Solution 1:

I used: easy_install -U pip problem solved

Solution 2:

Well, obviously there is an error with pip and unpack_url is probably use to download packages from PyPi. I suggest reinstalling by executing this script.
