I have the same problem I added the LD_LIBRARY_PATH, but it still does not work did you find any solution?

I meet the problem too. The solution in this issue https://github.com/openai/mujoco-py/issues/267 works for me.

use this commands in terminal

echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/user/.mujoco/mujoco210/bin' >> ~/.bashrc next source ~/.bashrc
