使用 pip 在 windows 7、python 3.4.3 上安装 cython

Question

我尝试通过

在windows 7 64位（Python 3.4.3）上安装cython

pip install cython

并以错误消息结束

 error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat).

我觉得有点奇怪，因为我安装了 visual studio community 2013。当我问 windows vcvarsall.bat 在哪里时，它友好地回答我

C:\Users\me>where vcvarsall.bat
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat

所以它就在我的路上。我是否需要不同的 visual studio 版本以及不同版本的 vcvarsall.bat？

编辑 1 我下载了提供的 VS2010 ISO SonicARG。谢谢你。现在 cython 承认编译器，但仍然无法安装。

Answer 1

Python 3.4 是针对 Microsoft 的 Visual Studio 2010 构建的；为了构建原生模块你必须使用准确的版本。您可以只下载 Express Edition 来构建它们，不需要整个 IDE。您可以获取 VS2010 ISO from here，并安装 C++ 组件，然后重试。

未来注意事项：如果您计划将 Python 升级到 3.5（发布日期为 2015 年 9 月 13 日），Visual Studio 版本将为2015，所以如果你有保存问题，你可以准备好
