issue: Problems with loading the drivers and opening swras

[harmfrima]

Issue: I encounter issues when running the simulation environment: gym_envs_urdf. I followed the README but get errors at the last step when I have to run the examples: python3 point_robot.py. It says I have problems with loading the drivers and opening swrast.

This is the error:

Clearly, the glib driver is the problem. Have you tried to install the missing dependencies, such as swrast through sudo apt install libgl1-mesa-dri?

Yes, I tried that earlier. Unfortunately it gives the same error.

I deleted the whole virtual machine and reinstalled the VM. Now it is working
