Issue

Using a clean environment on Python 3.11.4, running

pip install orbitize

Produces the following error:

Running pip install numpy does not help the problem. I was able to reproduce this on 2 different machines with and without virtual environments. I'm also using pyenv to manage Python versions, but I have confirmed that pip is installing packages to where they should be.

Solution

The solution I came up with was running:

pip install wheel

Then

pip install orbitize

seems to work.

Adding wheel to the requirements.txt does not fix the problem, you have to run pip install wheel separately.

Might be helpful to include this in the docs since it fails on a clean virtual environment. Not sure if there's a better way to fix this, might also be an issue with newer Python versions.

Thanks for the bug report @jsnguyen! I'll add this to our docs.
