I have a conda environment named tensorflow_p36. When I run import mujoco-py I get the following error:

Exception: Missing path to your environment variable.

Please add following line to .bashrc: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ubuntu/.mujoco/mujoco200/bin

Therefore, I add the line above to .bashrc:

(tensorflow_p36) ubuntu@ip-172-XX-XX-XXX:~$ echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ubuntu/.mujoco/mujoco200/bin' >> ~/.bashrc

and

(tensorflow_p36) ubuntu@ip-172-XX-XX-XXX:~$ source ~/.bashrc

This however does not add the environment variable to the conda environmnet. Such that when I run

ubuntu@ip-172-XX-XX-XXX:~$ echo $LD_LIBRARY_PATH

I get:

:/home/ubuntu/.mujoco/mujoco200/bin

but when I run from inside the virtual env

(tensorflow_p36) ubuntu@ip-172-XX-XX-XXX:~$ echo $LD_LIBRARY_PATH

I don't get the exported path showing. Any suggestions on how I can fix this?

What I've tried

I followed this answer:

cd $CONDA_PREFIX
mkdir -p ./etc/conda/activate.d
mkdir -p ./etc/conda/deactivate.d
touch ./etc/conda/activate.d/env_vars.sh
touch ./etc/conda/deactivate.d/env_vars.sh

I edited the env_vars.sh to include

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ubuntu/.mujoco/mujoco200/bin

Now when I run echo $LD_LIBRARY_PATH from inside the virtual env

(tensorflow_p36) ubuntu@ip-172-XX-XX-XXX:~$ echo $LD_LIBRARY_PATH

I get /home/ubuntu/.mujoco/mujoco200/bin:/home/ubuntu/.mujoco/mujoco200/bin

but the exception remains:

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/mujoco200/bin

I had the same issue but solved it by launching the IDE (PyCharm community in my case) from terminal via pycharm-communinity. I found this solutions in this GitHub Issue comment.
