Python not recognizing LD_LIBRARY_PATH

>>> import os
>>> os.system('echo $LD_LIBRARY_PATH')

0
>>>
ubuntu@ip-172-31-81-248:~$ echo $LD_LIBRARY_PATH
:/home/ubuntu/.mujoco/mjpro150/bin:/home/ubuntu/.mujoco/mjpro150/bin


For some reason, a package mujoco_py that I was trying to import kept complaining with the following message.



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/ubuntu/.mujoco/mjpro150/bin


I had made sure I had added the required path to LD_LIBRARY_PATH and on using os.system() I found out that the python shell is somehow not able to recognize the variable. What could the issue be?

    Did you export LD_LIBRARY_PATH - or just set it in the current shell?

  • I exported it and the line is also present in bashrc

  • Don't use os.system anyway. It is deprecated since ages and terribly outdated.

Add the export line



export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ubuntu/.mujoco/mjpro150/bin


to the .profile instead of the .bashrc.

    After you add that link to .bashrc you want to execute the following code.



    source ./bashrc


    Then the link is updated.
