setuptools_scm: Missing module name tomli

I just wanted to say a HUGE THANK YOU @RonnyPfannschmidt, for all your work on setuptools_scm and being able to quickly mitigate this issue.

In open source is easy to get a lot of attention when things stop working, without the much deserved appreciation the maintainers deserve.

i just returned to the computer to yank this release as well, it seems i will have to re engineer the way this is tested to stop missing those issues until reports pour in , a new release with the issue resolved will land later today

It appeared again with https://github.com/pypa/setuptools_scm/releases/tag/v6.3.0 release

Fix is already going up, no need to comment “Same here” https://github.com/pypa/setuptools_scm/pull/628

A well used package - Nine projects reported an issue within 16 minutes 😃

I can see that the METADATA file in the setuptools-scm 6.1.1 package pulls in tomli as part of an extra “tomli”, but it seems that Pip when it uses setuptools-scm under the covers does not install that extra, and setuptools-scm seems to depend on tomli even when the “tomli” extra is not installed.

So if tomli is really an optional extra, then setuptools-scm should not fail when it is not there. If it is required, it should not be an extra. At least IMHO.

+1 for that, the bad version was yanked within the hour and my builds are all ✅ again

Great work @RonnyPfannschmidt 🍰 ✨ 🏆 ⭐

Same here 🆘

Same here ! a Friday evening 🥲

Yes, I see it at https://readthedocs.org/projects/astropy/builds/14629185/

Same here occuring during the installation of black using pre-commit:

Same issue here. I’ve tried pip install tomli but no results.

Also experiencing the issue. Good vibes and happy Friday to all! ❤️

Thanks @RonnyPfannschmidt , you saved my Friday

Same, seeing CI failures because of this now.

cc @RonnyPfannschmidt who made the transition from toml to tomli in #586.

It’s a Friday evening and I’m sitting with a broken CI 😭

+1 Had the same issue and was just about to open an issue here 😉

In my case it happens when pip builds a wheel for the “lazy-object-proxy” package. We are not explicitly installing “setuptools-scm”, but it seems that Pip uses it under the covers when building a wheel.

Test run that fails: https://github.com/zhmcclient/zhmc-ansible-modules/pull/450/checks?check_run_id=3442020780#step:10:373

We’re also seeing this issue and it’s blocking all of our pip installs + builds

       pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.
