Answer 1

根据Anaconda ，您应该使用以下命令

conda install -c conda-forge gym-box2d

但你仍然可以只安装gym并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 健身房。 windows 的健身房安装不稳定。 官方支持 Linux 和 mac。 我推荐这个视频在 Linux、Windows 和 Mac 上安装 OpenAI Gym (gym[all])以安装在 Linux 上。 您可以在我尝试并工作的 windows 中使用 wsl2。

此外，这个 doc gym 0.7.4帮助我使用 wsl2 设置显示（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（占用大量空间，但没有其他选择）

Answer 3

I think you may go to https://www.lfd.uci.edu/~gohlke/pythonlibs/ and find pybox2d and download the version which match your python version and run pip install Box2D‑2.3.10‑cp38‑cp38‑win_amd64.whl （更改您的车轮名称！）
