Looks like this doesn't "just work":

Processing ./hatch_vcs-0.2.0-py2.py3-none-any.whl
ERROR: Could not find a version that satisfies the requirement setuptools-scm>=6.4.0; python_version > "3" (from hatch-vcs) (from versions: none)
ERROR: No matching distribution found for setuptools-scm>=6.4.0; python_version > "3"

@NorfairKing looks like the version of setuptools_scm probably is older in 21.11.

I think you either will have to update setuptools-scm to version 6.4.0 or higher (I see 21.11 branch uses 6.3.2). This will also affect many packages, but is preferred. The good thing about setuptools-scm is that it should be used only for building so if all packages still build successfully then likely upgrade works.

Alternatively you can see if hatch-vcs can work with older version and patch up the code to remove this requirement.

@takeda With nixos-22.05 around the corner, this is probably not worth it for now. Closing.
