Hi there,

I'm at a loss... nearly every time I try to release my Python library with maturin, one of the packages is refused by PyPI, which causes me to spend hours trying to fix a release. I've tried switching to uv but that also does not work.

Today's issue is with the MacOS 11 Python 3.13 builds.

Initially the MacOS 11.0 Python 3.12 was rejected with a 400 error
Then MacOS 11.0 Python 3.13 seemingly had the wrong name ... but the 3.12 was accepted after I reverted to the release code of my other library that worked perfectly not 24 hours prior.
Then that same wheel was corrupted after I switched all of my builds to be on Python 3.12.
Then trying to switch from no compression to the zstd compression was an error because zstd is not supported by PyPI ... I had switched to the no compression approach because the compression was repeatedly corrupted back in August.

What can I do here? I'm on my fifth attempt in two hours to release the Python package ... is this a PEBKAC? Or is this PyPI changing its accepted formats regularly? Or is it maturin being unstable for MacOS releases?

Any hint is appreciated, thanks

Sorry for the late reply, you can try to run twine check on these problematic wheels to see if there are any errors.

Hi there,

I just tried publishing a new version, and here we are again... https://github.com/nyx-space/anise/actions/runs/19421332305/job/55560509651

Any idea what I can do? If I try to rerun this, it still fails. I've spent all weekend working on this release because I need it for work in 8 hours... Now I can't use it because the publication failed on Python version 3.11 and we're on 3.13.

Ideally, I'd just disable Macos all together but I know many people use the Macos packages.

It isn't just Python 3.13 and 3.14 I guess...

For those who encounter this same issue, note that PyPI will accept new wheels for the same release on a new target.
