Unable to install mpi4py in MacBook M1

Question

I am trying to install mpi4py in MacBook M1. I am learning MPI and I wanted to test a basic "hello world" python program on my machine. However, I am facing difficulty installing mpi4py. I have tried solutions from this , this and this answers. Below is the entire error message I get in the terminal:

     note: This error originates from a subprocess, and is likely not a problem with pip.   ERROR: Failed building wheel for mpi4py Failed to build mpi4py ERROR: Could not build wheels for mpi4py, which is required to install pyproject.toml-based projects

I have downloaded wheel and upgraded pip, but haven't had any luck. Could anyone please tell me where I may be going wrong? Thanks in advance!

Try install using homebrew:

brew install mpi4py
