Cannot install mpich because conflicting formulae are installed. open-mpi: because both install MPI compiler wrappers Please `brew unlink open-mpi` before continuing. Unlinking removes a formula's symlinks from /opt/homebrew. You can link the formula again after the install finishes. You can `--force` this install, but the build may fail or cause obscure side effects in the resulting software.
