arro3 version in osx-arm (python 3.13)

[acocac]

@keewis are any workarounds to install arro3-cor from conda-forge in osx-arm? I get the following error under a conda environment:

When I type pip install -e ., it returns:

I believe it just isn't available on python=3.13, yet.

[acocac]

right - I confirm I can install locally xdggs when python==3.10. What's then the best developer practice in this case? should we declare the supported python versions in pyproject.toml?

[keewis]

I think that's what the classifiers are for: indicate which python versions are tested. We can't use upper bounds in requires-python because that leads to all sorts of issues.

I personally would develop on the most recent supported version of python (in this case, python=3.12).

[acocac]

That's fine - I just updated the title to specify the issue is with Python 3.13. Hope it's useful for others facing similar issues.

This is an upstream issue, so I'll go ahead and close this issue.
