Question

我在尝试安装/编译时遇到以下错误 ctools对于 python(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

错误:

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

我已经按照 here 中的建议安装了 PyWin ，但这没有帮助。如果能帮我解决这个问题，我将不胜感激。

编辑

尝试安装 scikit-learn 时出现同样的问题

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

我在我的博客中总结了以上内容。 http://springflex.blogspot.com/2014/02/how-to-fix-valueerror-when-trying-to.html

安装带有所有必需组件的 Visual Studio 2008 Express Edition:

1. 安装 Microsoft Visual Studio 2008 Express Edition。主要的 Visual Studio 2008 Express 安装程序可从以下位置获得(C++ 安装程序名称为 vcsetup.exe):

2. 安装 Microsoft Windows SDK。 Microsoft Windows SDK 可通过搜索 Microsoft 的下载站点或直接转到: http://www.microsoft.com/downloads/details.aspx?FamilyId=F26B1AA4-741A-433A-9BE5-FA919850BDBF&displaylang=en

3. 要验证您是否已安装所有组件，请检查 Microsoft SDK 是否包含 C/C++ 编译器“cl.exe”的“amd64”版本。这通常安装到

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

4. 复制 .../VC/bin/vcvars64.bat 到 .../VC/bin/vcvarsamd64.bat

5. 复制 .../VC/bin/vcvars64.bat 到 .../VC/bin/amd64/vcvarsamd64.bat
