Describe the bug

I was trying to install slim-cli via pip but it failed while trying to compile numpy.

Full log is here: build_log.txt

It looks like it could be related to python 3.13: numpy/numpy#24318

What did you expect?

I expected slim-cli to be installed successfully in my environment

Reproducible steps

micromamba env create -n slim "python=3"
micromamba activate slim
pip install slim-cli

Environment

I was able to downgrade to python 3.12 and pip install slim-cli worked without issue.

Hi @frankinspace - thanks for posting this ticket. Sounds like you had a solution for 3.12, but we'll take a look at 3.13 and see if we can make a permanent resolution. Appreciate the in-depth ticket!

Hi folks, can confirm that on brew-installed Python 3.13 on macOS 15.6.1 I get the same error. This occurs on a newer arm64 system and I could also reproduce it on an older amd64 system.
