error when trying to import gym_miniworld on Google Colab

See original GitHub issue

Before, I had no problems in running minigrid over Colab, however I have tried several options in order to run Miniworld over Colab but have not succeeded. At the beginning of my Colab notebook, I first install the following libraries:

!pip install rarfile --quiet
!pip install stable-baselines3 > /dev/null
!pip install box2d-py > /dev/null
!pip install gym pyvirtualdisplay > /dev/null 2>&1
!sudo apt-get install -y xvfb python-opengl ffmpeg > /dev/null 2>&1
!pip install gym-miniworld > /dev/null 2>&1

Then, the error appears right when importing the libraries:

import gym
import gym_miniworld

The error I get is the following:

Any suggestion on how to handle this? Many thanks!
