Hi, are there any fixes for this issue yet ?

[dylanashley]

This is just an issue with not having MuJoCo installed in your system. The older versions of mujoco-py require the older version of MuJoCo to work. You need to (1) download the version of MuJoCo that it references (150) from here, (2) extract it to the corresponding folder (~/.mujoco/mjpro150), (3) download the mjkey.txt from here, and (4) place the mjkey.txt at the root of your ~/.mujoco/ folder.
