Can't install petsc4py in Ubuntu

Hello,

I need to use open framework openMDAO for my project in Ubuntu. Which needs mpi4py and petsc4py, I have installed mpi4py using pip command $ pip install mpi4py.

But I am not able to install petsc4py using command $ pip install petsc petsc4py. It gives error as follows:

ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

I don’t have computer science background and this is the first time I am dealing with something like mpi.

I have Ubuntu 20.04.1 LTS and I am using Anaconda3 as well.

Can anyone please help ?
