Failed building wheel for healpy

[tombickleastro]

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

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:

note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for healpy Failed to build healpy ERROR: Could not build wheels for healpy, which is required to install pyproject.toml-based projects

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

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 https://github.com/BDNYC/sedkit/issues/118.
