[Zibri]

apparently is due to this: RuntimeError: Unsupported platform: mingw64_nt-10.0-19045. Please contact the scikit-build team.

[Zibri]

I know I can install mingw-w64-x86_64-ninja and mingw-w64-x86_64-python-numpy

just wondering why it fails if installed with pip

[lazka]

Someone would need to make scikit-build support MSYS2, I'd guess.

[lazka]

numpy now uses meson-python which works fine in MSYS2 (assuming the build dependencies are installed, pass "-v" if it fails to get details)
