【亲测】Python:解决方案：Python Version 2.7 required, which was not found in the registry

好久不更新随笔了，今天因为数据可视化作业，想抓取一些人人网好友关系数据，于是开始尝试python，用到numpy模块，安装的时候提示：

'Python Version 2.7 required, which was not found in the registry'

发现很多人都遇到这个问题，网上说是官方不支持包，然后给了另外的链接让去下非官方版的，结果没找到囧。。。

于是发现了这个帖子，直接解决了问题，果断贴过来，帮助其他和我一样遭遇的人儿们。

I'm running Python 2.7 on Windows 7 64-bit, and when I run the installer for setuptools it tells me that Python 2.7 is not installed. The specific error message is:

'Python Version 2.7 required, which was not found in the registry'

I'm looking at the setuptools site and it doesn't mention any installers for 64-bit Windows. Have I missed something or do I have to install this from source?

How to install SetupTools on 64-bit Windows?

Solution:

Apparently (having faced related 64- and 32-bit issues on OS X) there is a bug in the Windows installer. I stumbled across this workaround, which might help - basically, you create your own registry value:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\2.7\InstallPath

and copy over the InstallPath value from:

HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.7\InstallPath
