I had the same error, but in addition to installing setuptools-meta from github, I also had to remove all occurrences of that package from the setup.py, because python was still looking for setuptools-meta at pypi during the installation.

Packaging python code can unfortunately be pretty annoying. :/ An easy solution to this might be in https://github.com/noirbizarre/setuptools-meta/issues/1.

As an alternative, one could think about migrating the setup.py definitions to the more modern pyproject.toml infrastructure from PEP 518, that also allows properly specifying requirements to the setup environment. But I guess that this is again not compatible with setuptools-meta, which would then require changes to that library -- or our usage of it, which is only for providing debugging information about the somewhat broken packaging and installation, anyways.
