When attempting to install requirements.txt on Python v3.6+, an error occurs due to no Python 3 compatibility for the futures module.

I think this is just due to the fact that this codebase can only run on Python2. From futures docs here:

It does not work on Python 3 due to Python 2 syntax being used in the codebase. Python 3
users should not attempt to install it, since the package is already included in the standard library.

Ok, so remove it from requirements.txt and continue forth... got it! Thanks @sgnn7!
