TypeError: '<' not supported between instances of 'Version' and 'Version' when installing manually.

[TheChymera]

I understand setup.py is no longer recommended, but the error seems to be in comparing the string 'Version' to a version. Any idea where that might be happening?

For the record, it did eventually work, but required python setup.py develop --user --no-deps.

@TheChymera I don't believe this has anything to do with dandi (and if it does, it belongs on the dandi-cli repo, not dandischema). It looks more like a bug in setuptools (or possibly versioneer).

@TheChymera Likely related: pypa/setuptools#1383

@jwodder and sorry for opening the issue here, I think I landed on the wrong issues page tab :)
