Answer 1

根据Anaconda，你应该使用下面的命令

conda install -c conda-forge gym-box2d

但您仍然可以只安装 gym 和 from gym.envs import box2d

Answer 2

我认为您正在使用 windows 来使用不受官方支持的 openai gym。 windows 的健身房安装不稳定。 Linux 和 mac 得到官方支持。我推荐此视频 Installing OpenAI Gym (gym[all]) on Linux, Windows and Mac 用于在 Linux 中安装。你可以在 windows 中使用 wsl2，我已经试过了。

此文档 gym 0.7.4 还帮助我设置了使用 wsl2 的显示（根据文档别名 linux 服务器）。

像 box2d 这样的单独安装对我不起作用。尝试按照视频中的说明安装所有健身房环境（需要很多 space 但没有其他选择）
