为Python 2.7构建/安装C模块时出错

Question

我正在尝试安装/编译ctools for python 时获取以下错误(版本信息)

ActivePython 2.7.2.5 (ActiveState Software Inc.) based on
Python 2.7.2 (default, Jun 24 2011, 12:22:14) [MSC v.1500 64 bit (AMD64)] on win32

• 操作系统:Windows 7 Professional 64位(Service Pack 1)
• 已安装:Microsoft Visual C++ 2008 Express Edition

    raise ValueError(str(list(result.keys())))
ValueError: [u'path']

我按照这里的建议安装了PyWin ,但没有用.我很感激帮助解决这个问题.

编辑

尝试安装时会出现同样的问题 scikit-learn

  File "C:\Python27\lib\distutils\msvc9compiler.py", line 299, in query_vcvarsall
    raise ValueError(str(list(result.keys())))
ValueError: [u'path']

Answer 1

我在上面的博客中总结了一下. http://springflex.blogspot.com/2014/02/how-to-fix-valueerror-when-trying-to.html

要安装包含所有必需组件的Visual Studio 2008 Express Edition:

1. 安装Microsoft Visual Studio 2008 Express Edition.可以从(C++安装程序名称为vcsetup.exe)获得主Visual Studio 2008 Express安装程序:

2. 安装Microsoft Windows SDK.可以通过搜索Microsoft的下载站点或直接访问以下网址获得Microsoft Windows SDK:http://www.microsoft.com/downloads/details.aspx？FamilyId = F26B1AA4-741A-433A- 9BE5-FA919850BDBF& displaylang = en

3. 要验证是否已安装所有组件,请检查Microsoft SDK是否包含"amd64"版本的C/C++编译器"cl.exe".这通常安装在

   C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\cl.exe
   

4. 将.../VC/bin/vcvars64.bat复制到.../VC/bin/vcvarsamd64.bat

5. 将.../VC/bin/vcvars64.bat复制到.../VC/bin/amd64/vcvarsamd64.bat

Answer 2

一旦安装了适用于Windows 7和.NET Framework 3.5 SP1的Microsoft Windows SDK (安装Visual Studio 2008 SP1 Express Edition时未安装的64位编译器),就可以使用64位版本的Python了.您需要将其复制vcvars64.bat到vcvarsall.bat 声明它的位置.

从%CSIDL_PROGRAM_FILESX86%\Microsoft Visual Studio 9.0\VC\bin\,您需要复制 vcvars64.bat到amd64\vcvarsamd64.bat.

请注意目标文件名中的amd部分.
