安装Python第三方模块遇到Python version 2.7 required, which was not foundin the registry的问题

最近在学习Python，当需要安装到一些第三方模块的时候发现出现了

“Python version 2.7 required, which was not foundin the registry”

的问题，如下图：

网上搜了下，原来是因为安装Python的时候使用了all users可用的选项，如果选择仅本用户可用便不会出现这个问题，但是难道要重装？于是又找到了方法，便是将以下脚本保存，并运行，即可顺利解决问题，脚本代码如下（发现51cto的代码块不能缩进，已将代码放附件了）：

version  =  sys.version[: 3 ]
installpath  =  sys.prefix
regpath  =  "SOFTWARE\\Python\\Pythoncore\\%s\\"  %  (version)
installkey  =  "InstallPath"
pythonkey  =  "PythonPath"
pythonpath  =  "%s;%s\\Lib\\;%s\\DLLs\\"  %  (

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()

将以上代码保存脚本register.py后，在命令行下进入对应目录下运行命令“Python register.py”
