pip compatibility issues with installation

[taitleaney]

I'm having trouble installing Bluto. As far as I can tell, I'm using pip2 and python2.7 (within a virtualenv):

$ pip -V
pip 20.0.2 from /home/parallels/python2-venv/lib/python2.7/site-packages/pip (python 2.7)

$ python -V
Python 2.7.18

And this is the error I get:

ERROR: Command errored out with exit status 1:

By the looks of things, it is because python/pip 2 is no longer supported and running the script in python 2 generates the warnings which the script treats as an error. Has anyone found a work-around?

I'll try recreate the issue.
