Need conda-forge package for 3.12

[michaelaye]

At the moment there doesn't seem to be a package for Python 3.12?

❯ mamba install nb_conda_kernels astropy kalasiris

Looking for: ['nb_conda_kernels', 'astropy', 'kalasiris']

conda-forge/linux-64                                        Using cache
conda-forge/noarch                                          Using cache

Pinned packages:
  - python 3.12.*

I think you can transfer the issue on the following repository: https://github.com/conda-forge/nb_conda_kernels-feedstock

[michaelaye]

I guess, even so, it looks like issues aren't looked at over there.

If it helps, I recall from glancing at the logs (now not accessible unfortunately) that the error for 3.12 builds had to do with versioneer

[philip-khor]

Running pip install -e . on py312 returns:

Perhaps useful: python-versioneer/python-versioneer#375

pip install completes without errors after running versioneer install --vendor using master branch versioneer

[effigies]

The versioneer issue is resolved, but an old versioneer is vendored here. Upgrade with pipx run versioneer install.

See https://github.com/python-versioneer/python-versioneer/blob/master/UPGRADING.md for any migration issues.

I opened #236 after realizing that a naive update in the conda-forge feedstock (conda-forge/nb_conda_kernels-feedstock#53) didn't work.

Would be glad to have anyone look at my PR (#236).

[mcg1969]

fixed by #237 (and thanks to @basnijholt for #236, which drove it).
