python-解决安装MySQL-python出现的： Python version 2.7 required，which was not found in the registry

在安装MySQL-python-1.2.3.win-amd64-py2.7.exe时，提示：Python version 2.7 required，which was not found in the registry

这是在注册表不能识别python2.7，原因windows是64位，安装的python是32位。怎么查看自己安装的python是多少位的呢？因为32位、64位都可以在64位操作系统中安装，所以年代久远的时候，就不记得当时自己安装的python是32呢，还是64了。查看非常之简单。输入平时我们检查是否有python环境的命令即可：

C:UsersAdministrator>python

解决方法：

1.新建一个register.py文件，将如下代码copy进去：

#
# 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()

2.定位到该文件所在目录运行python register.py

说明python2.7已经注册成功。

3.再执行MySQLdb安装程序，则会自动识别，并安装成功了。
