I've placed the folder mjpro150 into ~/.mujoco and also placed the mjkey.txt in there.

I needed to

1. brew uninstall gcc
   > notifies that there is still a gcc@7 left in the system.
2. brew uninstall gcc@7
3. brew install gcc@8
4. pip install mujoco-py.

important-2019-09-21: @sungsulim is right about the gcc@6. gcc@8 was okay in the past, but for this different macbook I'm using now only the gcc@6 worked.

important: I made a mistake of including /bin in the MJPRO_PATH for mujoco-py. See third-line below:

export LD_LIBRARY_PATH=$HOME/.mujoco/mujoco200/bin:$LD_LIBRARY_PATH
export MUJOCO_PY_MJPRO_PATH=$HOME/.mujoco/mujoco200/
export MUJOCO_PY_MJKEY_PATH=$HOME/.mujoco/mjkey.txt

worked. In addition I had to do

brew uninstall gcc
brew uninstall gcc@8
brew uninstall gcc@9

brew install gcc@6

Only the gcc@6 worked with this installation. OSX version is 10.14.6 (18G87)

Note this is also true on Linux. It seems that mujoco-py likes the path without the platform post-fix, where as DeepMind dm_controlsuite likes it with those post-fixes.

[sungsulim]

For me it was somehow using gcc@6 and had to do

1. brew uninstall gcc
2. brew uninstall gcc@6
3. brew install gcc@8
4. pip3 install mujoco-py

It still did not work for me.
I am trying to run it on a mac and the full error is:

has anyone faced the same problem and found a solution for it?

[marjanin]

It worked for me once I installed the pkg mentioned here:
