[regression in 2.14.0] setuptools-scm was unable to detect version for '/wrkdirs/usr/ports/textproc/yq/work/yq-2.14.0'.

The FreeBSD package build fails:

It builds from the tarball downloaded from GitHub.

OK, I was able to reproduce the issue. It looks like you originally tried to pull the tag’s tarball from github. Note that the line immediately following your pasted snippet gives the explanation for the error:

  LookupError: setuptools-scm was unable to detect version for /private/var/folders/mg/s14fqnk1089g4jggcbyz2xnr0000gp/T/pip-req-build-nsqjbwin.

  Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

It’s unfortunate that with setuptools-scm raw tarballs from github don’t work, perhaps there is a way to hide them from the release. But setuptools-scm is the best way for maintainers to manage release versions so this will be a common issue.

Strangely, it builds with the tarball from PyPI.

So closing.

Thanks for your help!
