      I suspect this is because setuptools_scm isn't being used correctly. The function takes one argument, root, but judging from the code that uses it, it appears to expect a setuptools_scm.config.Configuration object rather than a file path.

      All the documentation says to use get_version() and the package author doesn't seem to be sure that version_from_scm() should even be a public function (see here). Perhaps going with that would be best.
