Mujoco-py: Mujoco issue with gcc on mac OS Catalina

[RyanRizzo96]

OS: [Mac OS 10.15]
Python Version [ 3.7.1]
Mujoco Version [Mujoco200]
mujoco-py version [2.0.2.6]

I'm completely stuck when trying to install Mujoco on Mac OS Catalina. I managed this on Mojave and countless Ubuntu machines in the past.

I use: pip install mujoco-py

I install gcc8 as suggested here but:

error: command '/usr/local/bin/gcc-8' failed with exit status 1
  ----------------------------------------
  ERROR: Failed building wheel for mujoco-py
  Running setup.py clean for mujoco-py
Failed to build mujoco-py
ERROR: Could not build wheels for mujoco-py which use PEP 517 and cannot be installed directly

I then try to use gcc6 as suggested here but:

  error: command '/usr/local/bin/gcc-6' failed with exit status 1
  ----------------------------------------
  ERROR: Failed building wheel for mujoco-py
  Running setup.py clean for mujoco-py
Failed to build mujoco-py
ERROR: Could not build wheels for mujoco-py which use PEP 517 and cannot be installed directly

I then try using pip3 install --no-use-pep517 -U 'mujoco-py<2.1,>=2.0' and I get:

 error: command '/usr/local/bin/gcc-6' failed with exit status 1
    ----------------------------------------

EDIT:

Here is a snippet of the full error:

Why is this happening on Catalina? How can I install mujoco? Let me know if you need full error logs. Thanks for any suggestions!
