Mujoco_py missing path to LD_LIBRARY_PATH, Ubuntu 16.04

Question

I am trying to get mujoco_py running. When I do

import mujoco_py

I get this error:
Exception:

Missing path to your environment variable.  
Current values LD_LIBRARY_PATH=  
Please add following line to .bashrc:  
export  LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/jonah/.mujoco/mjpro150/bin

I have added the above line to both /etc/skel/.bashrc and ~/.bashrc. If I run

echo $LD_LIBRARY_PATH

I get

/home/jonah/.mujoco/mjpro150/bin/

My .mujoco folder includes mjkey.txt and the mjpro150 folder. I can run ./simulate successfully, so I have a feeling that this is some kind of mujoco_py specific bug.

Which program do you use to import mujoco?

I had a similar issue using mujoco_py with PyCharm Community 2018.1. A workaround was to launch PyCharm from the terminal instead of using the launcher icon. Maybe it could help with your issue too.

Otherwise you could try adding the LD_LIBRARY_PATH to ~/.profile instead of ~/.bashrc, as proposed in this answer here: https://askubuntu.com/questions/1022836/python-not-recognizing-ld-library-path/1022913#1022913

You can try to reinstall Pycharm for the newest version.

Please check the user which you run the code with. The mismatch user will cause this problem. There is the checklist may help you:

Don’t use ‘sudo’ to run the code;
Don’t use ‘sudo’ or virtual environment (e.g., anaconda) to run Pycharm (If you run the code in Pycharm).
