Python version 2.7 required, which was not found in the registry

　　安装PIL的时候，不能再注册表中识别出来python2.7
　　在网上找了方法，仅作笔记，供下次使用
　　方法：
　　新建一个register.py 文件，把一下代码贴进去
　　

• 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()
  

　　

　　然后命令行切换到脚本目录运行：python register.py
　　显示：--- Python 2.7 is now registered!  则表示成功
