Regarding installation of Kapteyn.

[AstroAvijit]

When I am doing pip install https://www.astro.rug.nl/software/kapteyn/kapteyn-3.0.tar.gz, I am getting the following
error: command '/home/avijit_astro/mesasdk/bin/gcc' failed with exit code 1
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure

× Encountered error while trying to install package.
╰─> kapteyn

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.
I am using ubuntu 20.04.05 LTS and gcc version is gcc.exec (GCC) 10.2.0
Please guide me.

Hi, I have had the same problem when I tried to install Kapteyn. I fix this issue by downgrading the version of numpy to 1.22 . I don't what the issue is exactly but I know it doesn't install correctly for me with numpy versions 1.23 and 1.24. Hopefully this is helpful 🙂
