[转载]Python注册表信息丢失的解决方案

今天安装Python的模块时，安装失败，提示信息:Python version 2.7 required, which was not found in the registry.

原因在于Python在注册表中没有注册信息，需要手动添加：

 #
 # script to register Python 2.0 or later for use with win32all
 # and other extensions that require Python registry settings

 import sys

 from _winreg import *

 # tweak as necessary
 version = sys.version[:3]
 installpath = sys.prefix

 regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
 installkey = "InstallPath"
 pythonkey = "PythonPath"
 pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
     installpath, installpath, installpath
 )

 def RegisterPy():
     try:
         reg = OpenKey(HKEY_CURRENT_USER, regpath)
     except EnvironmentError as e:
         try:
             reg = CreateKey(HKEY_CURRENT_USER, regpath)
             SetValue(reg, installkey, REG_SZ, installpath)
             SetValue(reg, pythonkey, REG_SZ, pythonpath)
             CloseKey(reg)
         except:
             print "*** Unable to register!"
             return
         print "--- Python", version, "is now registered!"
         return
     if (QueryValue(reg, installkey) == installpath and
         QueryValue(reg, pythonkey) == pythonpath):
         CloseKey(reg)
         print "=== Python", version, "is already registered!"
         return
     CloseKey(reg)
     print "*** Unable to register!"
     print "*** You probably have another Python installation!"

 if __name__ == "__main__":
     RegisterPy()

将上面的代码保存为register.py 然后双击运行，问题即可解决。
