error: Cannot compile MPI programs. Check your configuration!!!
Installing mpi4py requires a working MPI implementation.
If you are running on a supercomputer or cluster, check with
the system administrator or refer to the system user guide.
Otherwise, if you are running on a laptop or desktop computer,
your may be missing the MPICH or Open MPI development package:
* On Fedora/RHEL systems, run:
$ sudo dnf install mpich-devel # for MPICH
$ sudo dnf install openmpi-devel # for Open MPI
* On Debian/Ubuntu systems, run:
$ sudo apt install libmpich-dev # for MPICH
$ sudo apt install libopenmpi-dev # for Open MPI
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
