ERROR: Could not build wheels for mujoco-py which use PEP 517 and cannot be installed directly

[amir-noohian]

I want to install mujoco-py on ubuntu, and I faced this issue. I tried different solutions mentioned in this page. However, none of them worked. I have been working on this issue for a while. Please tell me possible solutions.

I'm also getting the same error, following is the error trace:

I'm facing the exact same issue on my mac also. I haven't tried it with windows.

I suggest that you try it on Windows; it works fine on Windows.
