cloning this repo and running setup.py to install, however, DOES work. definitely something having to do with the pip package and not the program itself.

pip must have changed its API some time in the last 5 years. It's the fault of my setup script which used to (and apparently still does, in the latest published version) query installed packages to see if it could use a precompiled pillow-SIMD. I removed this logic in 1ad5b1fb0eadf797b42ef5435d804a6b438e19b0 but that hasn't been published on PyPI.
