Unable to install when using Python `3.13`

[HCookie]

Description of the problem

As of October 7th 2024, Python 3.13 was released.
However, pyshtools cannot be installed when using this 3.13. I have checked my system and on 3.12 it installs just fine.

See below for the build stack trace

Could you try installing from source? There are no wheels or conda packages yet for python 3.13.

Could you try installing from source?

Yes, I am able to install from source. However, downstream users / CI actions of a depending package may find those steps tricky.

There are no wheels or conda packages yet for python 3.13.

I am hoping to use this issue to notify when wheels or conda packages are available for Python 3.13.

I do understand that 3.13 just came out, so it is not an immediate requirement. Was just raising awareness of the current issue.

[MarkWieczorek]

I wasn't aware about 3.13, so I'll look into it. It might be easy to just rerun our release action to make and upload the wheels, but conda will probably have to wait until the next release (before the end of the year).

Thanks @MarkWieczorek, 3.13 kinda snuck up on me too.
Hopefully a rerun will solve the pypi issue

I just wanted to point out that, for Python 3.13 builds to get automatically created for PyPi, some small changes will need to be made to the build_wheels.yml GitHub workflow file.

Specifically, in the two places where pypa/cibuildwheel@v2.17.0 is mentioned, it will need to be replaced with pypa/cibuildwheel@v2.22.0.

We shouldn't need to do much more than that, though, as far as 3.13 support goes for the GH action.
