Can't pip install on Windows

[retroexpress]

Hello,

I've been trying to install using pip on Windows 10 and 11 in both Python 3.8 and 3.10 on multiple machines but encounter the following error due to paths specified in SOURCES.txt:

Hello @retroexpress,

Astrometry (this repository) does not work on Windows because Astrometry.net (the underlying C implementation) is not compatible with Windows. I started listing the changes that would be required to make Astrometry.net compatible with Windows here: https://github.com/neuromorphicsystems/astrometry#msvc-compatibility-work-in-progress (this is not a complete list).

You should be able to run Astrometry on Windows despite this issue by using WSL: https://learn.microsoft.com/en-us/windows/wsl/install
