Failed building wheel for healpy

[tombickleastro]

I can't pip install on my windows machine, as it fails to download healpy properly.

[kelle]

Can you tell us more about your configuration. What version of Windows? Are you using WSL? Could you post the error message? Thanks!

[tombickleastro]

Sure - i'm on Windows 11. No WSL.

Error is:

I'm gonna be honest with you: in my many years of running computing workshops and supporting/mentoring folks with a wide variety of machines, the only way I've ever found to make scientific computing work on a Windows machines is via WSL. WSL lets you run a Linux environment inside Windows and gives you a real Linux command line.

The install instructions are pretty good and the default Ubuntu installation is a fine choice: https://learn.microsoft.com/en-us/windows/wsl/install

[kelle]

Also, when is the last time you tried to install? We've recently made some packaging improvements which seemed to have fixed this healpy installation problem for other windows users: see #118.

[kelle]

I have confirmed with the other Windows user that they got it to install under WSL/Ubuntu.
