在windows 7上安装python, python 3.4.3与pip

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，因为我已经安装了visual studio community 2013。当我问windows vcvarsmall .bat在哪里时，它亲切地回答我

C:Usersme>where vcvarsall.bat
C:Program Files (x86)Microsoft Visual Studio 12.0VCvcvarsall.bat

所以它在我的路径上。我需要一个不同的视觉工作室版本，并与vcvarsall.bat的不同版本?

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

Answer 1

Python 3.4是基于微软的Visual Studio 2010构建的;为了构建本机模块，您必须使用确切的版本。您可以下载Express Edition来构建它们，不需要整个IDE。你可以从这里获取VS2010的ISO文件，并安装c++组件，然后再试一次。

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)，那么Visual Studio版本将是2015年，因此如果您遇到保存问题
