在 Windows 上安装 SciPy 时遇到问题 [英] Trouble installing SciPy on windows

问题描述

我安装了 Python 2.7 和 NumPy.我已经为 SciPy 下载了预构建的二进制文件，但安装脚本失败并出现以下错误:

I have Python 2.7 and NumPy installed. I have downloaded pre-built binaries for SciPy, but the install script fails with this error:

Blas (http://www.netlib.org/blas/) 未找到库.搜索库的目录可以在numpy/distutils/site.cfg 文件(部分 [blas])或通过设置BLAS 环境变量.

Blas (http://www.netlib.org/blas/) libraries not found. Directories to search for the libraries can be specified in the numpy/distutils/site.cfg file (section [blas]) or by setting the BLAS environment variable.

我真的不太了解这个，无法愚弄它.我认为这是一个简单的安装过程，但似乎不是.我用谷歌搜索了 BLAS 环境变量，但找不到任何合适的东西.任何帮助表示赞赏.

I really don't know enough about this to fool with it. I assumed it was a straightforward install process, but doesn't appear to be. I googled for the BLAS environment variable, but couldn't find anything that seemed appropriate. Any help is appreciated.

没关系，我找到了一个非官方的安装程序 exe.

Nevermind, I found an unofficial installer exe.

推荐答案

要在 Windows 上安装 SciPy，您必须安装 Fortran 编译器.SciPy 项目推荐 MinGW.请参阅构建和安装 SciPy.要安装 MinGW，请遵循以下说明:HOWTO 安装 MinGW (GCC) 编译器套件.然后在运行 pip 或 easy_install 来安装 SciPy 之前，请确保您已将 MinGW 添加到您的路径中.请参阅 MinGW 安装说明 - 环境变量

To install SciPy on Windows you have to have a fortran compiler installed. The SciPy project recommends MinGW. See Building and installing SciPy. To install MinGW follow these instructions: HOWTO Install the MinGW (GCC) Compiler Suite. Then before you run pip or easy_install to install SciPy make sure that you have MinGW added to your path. See MinGW Installation Notes - Environmental Variables

附注，使用 Enthought Distribution (初始安装的一部分)或 Active State Distribution(仅通过 pypm 32 位)，因为他们已经为 SciPy 提供了预编译的二进制包.或者，您可以使用 SciPy 预编译二进制Windows 软件包安装程序.

A side note, It would be easier to use either the Enthought Distribution (part of the initial install) or the Active State Distribution (through pypm 32-bit only) as they already have precomiled binary packages for SciPy. Or, you could use the SciPy precompiled binary package installer for Windows.
