Dear foamers

I faced the following error during the installation of OpenFOAM-7 from

https://openfoamwiki.net/index.php/Installation/Linux/OpenFOAM-7/Ubuntu/20.04

on ubuntu 20.04, when I use this command:

./makeParaView -python -mpi -python-lib /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 > log.makePV 2>&1

vtkmpi4py/src/MPI.c:4:

Do you know how to solve it?

Thanks
