I am trying to install mujuco onto my linux laptop and everything works until I try to import it into a python file. When I try to import it/run a python script that already has mujuco in it I get the following errors:
Import error. Trying to rebuild mujoco_py.

I have gcc 11.0.2 installed and I'm using python3.8 in my virtual environment. Here are my exact steps https://docs.google.com/document/d/1eBvfKoczKmImUgoGMbqypODBXmI1bD91/edit
Everything works accordingly until the very last step where I try to run an actual python module
I really don't know why this is happening and I've tried just about everything on the internet. I would really appreciate it if someone can help.
Where does /home/daniel/miniconda3/envs/mujoco_py/lib/libstdc++.so.6 come from? Something bundles a version of libstdc++.so.6 which is older than your system version, and other system libraries depend on the newer version. You should be able to fix this issue by just deleting the file in your home directory.
