我尝试了中 windows 的所有解决方案，但没有结果。

如何安装 Box2D 以及 swig 的错误代码 1 是什么意思？

Answer 1

在此处下载 swig：http://www.swig.org/download.html

在某处解压存档，将解压目录的路径添加到您的 PATH 环境变量中。

重新启动您的 cmd 控制台 window（关闭并重新打开），执行您的 pip install Box2D

需要说明的是，在anaconda环境下，只加路径，也是不行的。我们需要使用 pip.exe 继续脚本。和运行命令！

Answer 2

我对 Box2D 有同样的错误。
我的解决方案- 从 http://aka.ms/vcpython27 下载适用于 Python 2.7 的 Microsoft Visual C++ 编译器完成安装。
然后在anaconda提示符下输入命令 'pip install Box2D'
然后键入 'pip install gym[all]'
这将安装剩余的依赖项。

希望对您有所帮助。

Answer 3

我在 Box2D 上遇到了同样的错误，但解决如下。

我正在使用 python3.6.

的 Anaconda 环境

试试这些。

conda install swig

pip install box2d

Answer 4

你好，我一定是迟到了，但我希望这能帮助某人解决他的问题。

只需使用 choco 或 conda 之类的包管理器或任何其他包管理器将 swig 包安装到您的机器上，然后运行安装 box2d 的命令再次.

choco install swig

pip install box2d-py
