The process for installing this package is supposed to be straightforward, but I am not really sure what's going on with this environmental naming error that keeps popping up no matter what I try.

I followed this https://github.com/openai/mujoco-py/issues/83 after reinstalling mujoco-py and doing all the steps here https://github.com/openai/mujoco-py under "Install MuJoCo".
System:
in mujoco_py/mjlib.py, changed bin/mujoco131.lib --> bin/mujoco131.dll
in mujoco_py/platname_targdir.py, changed sys.platform.startswith("windows") --> sys.platform.startswith("win")
Here's proof that it works now thanks to this https://github.com/openai/mujoco-py/issues/83:
