问题描述：

windows7 64 下安装 MySQL-python-1.2.4b4.win32-py2.7.exe报错：

python version 2.7 required,which was not found in the registry.

如下图：

安装时提示需要python2.7，但是此时python2.7已经添加到环境变量中.

解决方法：

在D盘新建register.py的文件，内容如下：

#
# 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()

然后运行这个python文件，效果如下：

然后在重新安装就没有问题了。
