This issue looks to be related to a _severe_ issue with cffi. May be related to similar causes to #7  - although I doubt it given that the OSes are different.

cffi==1.7.0 will not work on Python 3.8. This repo has been updated but doing pip install gets the older code.

I'm also getting an issue with the installation of libmagic. Here is the output:

If by any chance, python-magic has a dependency of libmagic, then download the libmagic libraries from pip install "python-magic-bin".

This would solve your problem.
