I've strictly followed the setup tutorial provided by gym However, I receive an error when I run pip install -e '.[all]'
or pip install -e '.[box2d]'

Failed building wheel for box2d-py
I omit some warning messages for briefness. I've done a lot of search, but still nothing works. I hope someone could help me figure it out. Thanks in advance.
Looks like you don't have the Anaconda Compilers installed. The newer versions of Anaconda ship with their own compilers. You can refer to this article on how to set it up properly.
In case you have installed the toolset already, make sure that you activate the appropriate environment since this will also set the necessary environment variables (deactivate / activate might also help after an update).
