Upgrading to setuptools >= 58 breaks the build

django-yubin depends on pyzmail36, which is a fork of pyzmail that does install on python 3.6+ (supposedly).

This relies on the use_2to3 keyword (https://github.com/ascoderu/pyzmail/blob/master/pyzmail/setup.py#L104) to convert the Python 2 code to Python 3 at package installation time ( 🤯 ).

Setuptools 58 removed this parameter, so now we get Python 2 code in our build which breaks things.

For the time being, I'm pinning setuptools to < 58.0 in CI etc. and keeping track of the issue here.

You might want to switch to demjson3 in case you really only want to support Python 3 anymore.

Thanks for the comment - but we don't use demjson, we just found that repository when investigating the setuptools issue and it was a good hint to figure out what was going wrong!

Fixed via 3e9a8ea, django-yubin dropped pyzmail36
