本文提供了一个Python脚本，用于解决在Windows环境下安装numpy时出现的注册表未找到Python版本的问题。通过修改注册表中的Python路径，使得系统能够正确识别已安装的Python版本。

python registry函数语法

在windows下安装numpy的时候, 出现了"Python version 3.4 required, which was not found in the registry"的错误.

类似的有:Python version 2.7 required, which was not found in the registry

大致意思是说:注册表没有对应的信息. 只要执行一个python脚本,将HKEY_CURRENT_USER (HKCU)注册就好.

2.7版本的可以参照: http://blog.youkuaiyun.com/zklth/article/details/8117207

3.4版本的可以参照: https://gist.github.com/embray/6042780#file-win_register_python-py
