No module named 'mujoco_py.mjlib'

Hi.
I'm trying to run the code on Linux Mint.
With pendulum environment, it works perfectly. But when I try to run with Mujoco environments, I get the following error (I installed mujoco & mujoco-py):

I had to install an older version of mujoco_py with mujoco131

Is there any way to know what is causing the issue in the first place? I am getting the same issue on my mac and have followed all the instructions as mentioned in the README.md page.

The older version does not work with Mac as listed here: openai/gym#638
