Unable to install from sdist: pyproject.toml [project] requires a name.

[mvaled]

This started to happen since yesterday in some CI environments using python:3.10-bullseye image. However, the CI jobs using python:3.8-bullseye and python:3.9-bullseye don't fail.

I've seen this in two different project: one uses tox to manage the virtualenv, the other one uses poetry. I don't really know why they are preferring the source dist over the binary wheels.

For those looking for a quick fix because you're trying to deploy to prod on a Friday night like me 😅

I forked mvaled 's fix to make sure it doesn't go anywhere. Thank you @mvaled ❤️

You can use that forked version in your requirements.txt file like this:

# requirements.txt

# ... 
falcon==1.4.1
gunicorn==19.9.0
git+https://github.com/treharne/immutables@avoid-issue-7#egg=immutables
Jinja2==3.0.3
lxml==4.4.1
# ...

I will keep this fork available at least until it "just works" without it (i.e. an underlying fix is provided for immutables and/or setuptools is adjusted), since we are using it in prod!

Hi @treharne PR #78 is now merged and they released 0.17 to pypi (#81). Even better they are now distributing a wheel for Python 3.10. I didn't even know they were not building for Python 3.10 before 😂.
