Have you checked the solution described in that message?

With the current openmpi-3.1.3-1 the before missing links are not
missing anymore.  So that shouldn't be the problem.

In detail I mean, check that /usr/bin/opal_wrapper.exe exists, and
/usr/bin/{mpic++,mpicc} also exist, and are links to the former.

Maybe before that, check that you have the latest version installed.
