Failed installation: error with Message Passing Interface in Ubuntu

PyLith
1

I’ve installed pylith and now at the validation stage Verifying Pylith

When trying to run the examples/box-2d it throws this error:
pylith step01_axialdisp.cfg
nemesis: error while loading shared libraries: libmpi.so.12: cannot open shared object file: No such file or directory

  1. Indicate which PyLith version you are using: pylith-4.2.0-linux-x86_64, binary

Is this something likely related to my Ubuntu version, or to the pylith install?

This error is most likely related to conflicts in your environment. Before you run source setup.sh, we recommend purging all unnecessary information from PATH, LD_LIBRARY_PATH, and PYTHONPATH. In most cases, PATH can be set to /usr/bin:/bin:/sbin:/usr/sbin and LD_LIBRARY_PATH and PYTHONPATH should not be set.

PATH=/usr/bin:/bin:/sbin:/usr/sbin
unset PYTHONPATH LD_LIBRARY_PATH

You should not have a Python virtual environment activated as PyLith uses its own Python virtual environment.

Understood! Thank you very much. This is probably a good reason to attempt using Docker instead
