在安装python 3.5的numpy时遇到问题

Question

我已经尝试了2个多小时来为python 3.5安装numpy模块

由于某种原因，我总是在最后收到此错误

building library "npymath" sources
No module named 'numpy.distutils._msvccompiler' in numpy.distutils; trying from distutils
error: Unable to find vcvarsall.bat

我从其他人那里读了很多关于这个问题的书。 但似乎无法找出如何为我修复它。

我有：

Microsoft Visual c ++ 2013可再发行

Microsoft Visual c ++ 2012可再发行

Microsoft Visual c ++ 2010可再发行

任何帮助都会很好！

谢谢

ps这是完整的输出

Answer 1

该问题与VisualStudio（默认）安装有关。

在安装VS 2015社区版本时，通常会选择默认的快速安装，该安装不包括语言支持工具，包括Python。

因此，您应该在一开始就在安装菜单中包括“编程语言”选项。 否则，将安装VC2015，但未安装Python支持。

Answer 2

嗯，构建NumPy不需要MSVC中的Python支持-如果您喜欢Visual Studio，它只是一个接口，可让您使用MSVC编辑Python文件。 NumPy实际上仅使用C ++编译器。 vcvarsall.bat只是为您将MSVC构建的环境变量设置为便捷功能，而NumPy在您尝试构建时找不到它。 我认为您正在尝试进行自定义安装？ OpenBlas还是什么？ 只需在线下载二进制文件，您就可以找到ATLAS版本和MKL http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy ，然后您就可以避免从源代码进行构建的麻烦（这是一个主要的麻烦我的意见）...哦，顺便说一句，您不能使用Visual Studio 2013安装任何适用于Python 3.5的软件包，它是使用Microsoft Visual Studio 2015构建的，因此，如果使用https：//www.visualstudio ，请下载2015社区版本。 com / en-us / products / visual-studio-community-vs.aspx使用python setup.py install编译软件包时，您也将需要它。
