can't install gi?

[Caltonian2]

I've tried so many different ways to access this module and yet when I run the ./run.sh in the target folder I get the following: Traceback (most recent call last): File "scripts/sc-controller", line 11, in import gi ImportError: No module named gi

trying to run 'pip install gi' won't work, trying to install it via python-gi won't work, trying to install various python related things won't work, and it seems like the computer thinks the thing is already installed when it isn't. What should I be doing?
