Cannot run on Windows10

[eblis]

What's the bug all about?

I've found out about the project and wanted to use it to upgrade my libraries but cannot get it to run successfully.

What command led to this issue?

$ pipupgrade --verbose

I can run the command myself though:

"c:\Program Files\Python38\Scripts\pip.exe" --version
pip 20.2.4 from c:\program files\python38\lib\site-packages\pip (python 3.8)

pipupgrade==1.7.4
