virtualenv ERROR: the executable in env/bin/python is not functioning

Question

The Problem

I am having great difficulty getting virtualenv to work on my OSX machine. When I run virtualenv env I get the error:

New python executable in env/bin/python
ERROR: The executable env/bin/python is not functioning
ERROR: It thinks sys.prefix is '/Users/tylerwendlandt/Documents/Courses/cmput_401' (should be '/Users/tylerwendlandt/Documents/Courses/cmput_401/env')
ERROR: virtualenv is not compatible with this system or executable

I tried looking around for solutions - but I can't seem to get it to work. I don't work with python very often, so this is mostly unfamiliar to me. I attempted to include the needed information, please let me know if more is needed. I appreciate any help - thank you.
