Python netifaces 模块 Windows 安装

Question

我的项目需要使用 netifaces 模块，但我无法获取它。我尝试通过 easy_install 安装源代码，但每次我收到此消息:

error: Unable to find vcvarsall.bat

我在 StackOverflow 中读到了一些有关此错误的答案，但我无法理解它......

有netifaces的编译版本或安装程序吗？非常感谢!

编辑1:安装 Visual Studio C++ 后出现此错误..有帮助吗？

Netifaces是根据c99标准编写的。特别是，代码使用混合声明和代码。不幸的是，微软的编译器不遵守该标准，并且不理解这种混合(编译 *.c 文件时)。我的解决方案是简单地将源文件重命名为“netifaces.cpp”。这样，MS 编译器就可以进行 C++ 构建，其中允许混合声明和代码。该文件的重命名还使得需要编辑“setup.py”来更改其中的文件名。
