pip installgynasium[box2d] 无法在 Google Colab 上运行

Question

我已经在gymnasium环境中工作了几个星期，通过在笔记本中使用以下命令，我在Google Colab中没有遇到任何问题：

pip3 install gymnasium[box2d]

但是，在不更改任何内容的情况下，我尝试再次运行该命令，但它突然停止正确安装 Box2d。

我得到以下输出：

我尝试更改gymnasium的版本，甚至只是从gym安装，但错误仍然存在。我不知道发生了什么事，因为昨天我对此没有任何问题。

Answer 1

我遇到了同样的问题。经过一番挖掘和大量试验和错误后，我能够通过首先运行

pip install swig

来让它工作。

希望有帮助。

Answer 2

以下对我有用

!pip install -q swig
!pip install -q gymnasium[box2d]

Answer 3

我没有使用 Google Colab，但遇到了同样的问题，但是这个命令解决了我的问题：

pip install wheel setuptools pip --upgrade

然后我就可以安装了：

pip install swig
pip install gymnasium[box2d]
