conda config --append channels conda-forge and
conda install mpi4py==3.0.0 works for me.

pip install mujoco_py would not work.
pip install mujoco_py==2.0.2.8 works for me.

pip install 'gym[all]' would not work.
sudo apt-get install libosmesa6-dev and
conda install 'gym[all]' work for me.

Add lines below into .bashrc
export LD_LIBRARY_PATH="/home/[YOUR_USER_NAME]/.mujoco/mujoco200/bin:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/include/GL/"

Encountering "cannot find -lGL" error,
