I have been working with the gymnasium environment for some weeks now and I had no problems with it in Google Colab by using this command in the notebook: pip3 install gymnasium[box2d]
However, without changing anything I try to run the command once again and it suddenly stopped installing Box2d properly.
I get the following output:

I tried changing versions of gymnasium and even installing simply from gym, but the error persists. I don't know what's going on because literally yesterday I was not having any problems with this.
I was running into the same problem. After some digging and quite a lot of trial and error, I was able to get it to work by first running pip install swig.
I hope that helps.
