python + 导入 C++ 编码帮助。 MSVCCompiler 缺少 compiler_cxx 修复程序；无法找到 vcvarsall.bat

Question

我有 scipy 和 numpy。所以我安装了 MinGW 以及 Cygwin。我将路径 o MinGW 添加到我的 环境变量。但是当我运行我的 python 代码时，它会显示此错误消息。

*numpy.distutils 中没有名为 msvccompiler 的模块；从 distutils 尝试 缺少针对 MSVCCompiler* 的 compiler_cxx 修复

那我现在该怎么办呢？我有一个 MSVCCCompiler。

当您谈论 C++ 编码时，我假设您想要编译 C/C++ 扩展。我使用 MinGW 在 Win32 上编译 C 扩展的方法是显式附加编译器:

python setup.py build_ext --compiler mingw32

如果你想为 Win64 编译，MinGW 似乎不是最好的选择。我使用了提示 here和 here并使用 Microsoft SDK 中的 VC++ 10 编译我的扩展。
