Installation Failure on Windows

Hello, I am trying to install the py3nj package through pip and I get the following error:

  The Meson build system

  Need python for x86, but found x86_64

I am using Windows 11, and had to manually download a FORTRAN compiler to solve a previous error.

It seems like you are running python for 64bit on an 32bit machine?

[gerardPlanella]

My machine is a x64 based PC. The print being shown by the FORTRAN compiler is incorrect.

Hum. It is weird.

Are you sure that you are running MinGW_x64? Or if you don't need to stick to MinGW, try quickstart-fortran https://github.com/fujiisoup/py3nj#installing-fortran-to-windows
