I opened an issue on GitHub and the SM team is looking into either making it a dependency that gets picked up by the script to make sure you have the python 2 version of setuptools, or altering the script to also work with python 3.
For the moment I've got my environment though I don't have time to mess with it as I'm busy with a work project. But I hope to spend some time with this soon.
