python要在Visual Studio 2015(v 14)中编译缺少vcvarsall.bat [英] vcvarsall.bat needed for python to compile missing from visual studio 2015 ( v 14)

问题描述

我正在尝试在装有Visual Studio 2015 Ultimate的Windows 10下的python 3.5中安装numpy.

I am trying to install numpy in python 3.5 under windows 10 with visual studio 2015 ultimate installed.

简短版本:vs14文件夹C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC文件夹中缺少文件vcvarsall.bat.为什么?

Short version: file vcvarsall.bat is missing from vs14 folder C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC folder. Why?

长版: 运行pip install numpy会给我这个错误error: Unable to find vcvarsall.bat

Long version: Running pip install numpy gives me this error error: Unable to find vcvarsall.bat

研究此错误使我获得了几个stackoverflow答案，这些答案帮助我弄清楚python需要c ++编译器来编译某些软件包.并且它需要使用用于编译python 3.5的同一版本的编译器来执行此操作( 错误:找不到vcvarsall.bat ).我的python使用[MSC v.1900 64位(AMD64)]进行编译-vs 14(Visual Studio 2015)

researching this error got me to several stackoverflow answers that helped me figure out that python needs c++ compiler to compile some of the packages. And it needs the to do it using the same version of compiler that was used to compile python 3.5 ( error: Unable to find vcvarsall.bat ). My python is compiled using [MSC v.1900 64 bit (AMD64)] - which is vs 14 ( visual studio 2015 )

随着研究的深入，我从以下中学到了知识: pip安装会导致错误:无法找到vcvarsall.bat 那 $python_install_prefix/Lib/distutils/msvc9compiler.py中的get_build_version()返回应用于查找vcvarsall.bat路径的vs的版本 对我来说，此方法返回14.所以一切正确.

Moving further with my research i learned out from: pip install gives error: Unable to find vcvarsall.bat that get_build_version() from $python_install_prefix/Lib/distutils/msvc9compiler.py returns the version of vs that shoud be used to find the path of vcvarsall.bat For me this method returns 14. So everything correct.

现在，当我查看文件夹C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC时，缺少vcvarsall.bat文件.

Now when I look into the folder C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC there file vcvarsall.bat is missing.

但是当我查看文件夹C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC时，有一个vcvarsall.bat.

But when I look into the folder C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC there is a vcvarsall.bat.

为什么vs 14.0中缺少vcvarsall.bat?

Why is vcvarsall.bat missing from vs 14.0 ??

推荐答案

确保在Visual Studio中安装了C ++通用工具.

Make sure C++ Common Tools are installed in Visual Studio.

程序和功能-> VS 2015->更改

Programs and Features -> VS 2015 -> Change
