OSError: /home/yzc_20/.mujoco/mujoco-2.1.1/lib/libmujoco.so.2.1.1: cannot open shared object file: No such file or directory` I don’t know how to fix this bug, hope for your reply, thx!~

@gemcollector You don’t need a license anymore. Here’s a script that’s been working for me. Note I don’t even need to define LD_LIBRARY or MJLIB_PATH and everything works smoothly.

1. Rename your old mujoco directory to mujoco_temp or just delete it.
2. Run the following script:

#!/usr/bin/env bash
#
# This script installs Mujoco 2.1.1.

wget https://github.com/deepmind/mujoco/releases/download/2.1.1/mujoco-2.1.1-linux-x86_64.tar.gz
tar -xf mujoco-2.1.1-linux-x86_64.tar.gz
mkdir -p ~/.mujoco
mv mujoco-2.1.1 ~/.mujoco
rm -r mujoco-2.1.1-linux-x86_64.tar.gz

# Install GLFW and GLEW for hardware accelerated rendering.
sudo apt install libglfw3 libglew2.1 libglew-dev

I find the problem. It is important to install a correct version of mujoco-2.1.1: mujoco-2.1.1-linux-x86_64.tar.gz I didn’t install a x86 version. @kevinzakka thx for your instruction and thx @saran-t for your reply! I have solved problem!
