ERROR: Could not build wheels for mpi4py, which is required to install pyproject.toml-based projects

I want to install mpi4py. The installation fails with the error below. Please share the solution to the same error.

  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

[notice] A new release of pip available: 22.3 -> 22.3.1
[notice] To update, run: python -m pip install --upgrade pip

I installed pyproject-toml with "pip install pyproject-toml". But mpi4py still won't install. My python version is Python 3.8.0.

I had a similar problem, but for me it had additionally something about not finding Python.h. I recently upgraded python version, and the problem was solved (as described here) via sudo apt-get install python3.X-dev (in my case X was 10).

I had the same error message. I used the Anaconda-Navigator interface and it worked fine.

Another option is to use brew. If OpenMPI isn't a dependency issue for you, the installation worked when I used it as well.

brew install mpi4py

For me it worked when I used sudo before:

sudo pip install mpi4py
