Cannot import anything from psychopy

When I try to import anything from psychopy, it errors. I have no issues with running this on my personal laptop, but when I try to run it on my Mac Mini, it errors.
I’m trying to run this on OS X 10.6.8. I installed all the packages via pip.

The code does not make it past initializing the import.

print("AAAA")
from psychopy import visual, event, core
print("@@@@@")

Here is what happens when I run my program:

AAAA
