Here is what that gave me just now for the main branch:

Expected behavior Tox runs through.

There are some notes at https://github.com/WDscholia/scholia/issues/2081

I do not get this commit a812e58400eae3af3eac62196b48803893fba0c6 completes tox with no problem...!?

[carlinmack]

I just checked out master and ran tox:

I'm not sure how tox accesses the different versions of Python, I don't think I have 3.7 installed

[fnielsen]

The different Python versions needs to be installed. I have used deadsnakes in some cases.

[fnielsen]

I can make it complete now:

  flake8: commands succeeded
  pydocstyle: commands succeeded
  py37: commands succeeded
  py38: commands succeeded
  py39: commands succeeded
  congratulations :)

I am not sure what was wrong, but it seems to run ok now., - as far as I can tell.

Please reopen if there still is a problem.
