I cannot simply reproduce what you described in installation tutorial. Each time I run, I will get the error in the image.

It seems the latest Gym has removed something about GoalEnv which leads to the error. It seems to be related with the latest update. Can you fix it? Or add some requirement of the gym version. 1

Hi, thank you for reporting. Indeed, GoalEnv has been removed from dev version of Gym. But the current stable version installed with pip is 0.21.0. If you install gym with pip you shouldn't encountered the error. Try

pip install gym==0.21.0

I leave this issue open to remember that the next gym version will require an update of the dependencies.
