MySQL-python-1.2.4b4.win32-py2.7提示报错，无法安装的解决方案

什么是MySQLdb?

MySQLdb 是用于Python链接Mysql数据库的接口，它实现了 Python 数据库 API 规范 V2.0，基于 MySQL C API 上建立的。
安装MySQLdb，请访问 http://sourceforge.net/projects/mysql-python ，(Linux平台可以访问：https://pypi.python.org/pypi/MySQL-python)从这里可选择适合您的平台的安装包，分为预编译的二进制文件和源代码安装包。

安装时报错

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，要解决这个问题，可以使用如下的方法：

在D盘新建register.py的文件或者新建一个register.py文件粘贴到D盘根目录下，内容如下：

# 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：

然后再去重新安装就没有问题了。
