Error when running the four environment files of multi-agent-emergence-environments

[aslansd]

I encounter the follwoing error when I want to run the four environments in "/multi-agent-emergence-environments-master/mae_envs/envs" folder:

During handling of the above exception, another exception occurred:

"mjmodel.h" is already in "/mujoco/mjpro/include/mjmodel.h". So my question is that most probably the environment files or more specifically "cymj.c" is not able to find "mjmodel.h" due to some problem in installation, or is there any other reason? Thanks!
