I even tried just using the word pip and an error said 'pip' is not defined. I'm not sure if I'm not using some syntax wrong, or if its a completely different issue.

It sounds like you are trying to install it from inside python. First 
make sure that pip is installed on your OS. Then install PyVISA from 
your commandline/terminal (which ever your OS provides). Also depending 
on which version of python you are using (2 or 3) you may have to type 
pip3 instead of just pip.
