Forced downgrade of six in python 3.8 crashes pip in venv

[phanuelayuka]

My virtual env is using python 3.8
When I install PyVimeo, six if forcefully downgraded from six 1.14.0 to six 1.10.0. This breaks the entire venv and pip stops working throwing the following error.

(venv) phang@phang:/media/phang/PRO/bafundecore$ pip freeze

Can you try restesting with the latest version? https://pypi.org/project/PyVimeo/#history
