python2.7安装MySQLdb模块（以及安装出现的问题和解决方式）

1、安装MySQLdb

我的Python的版本为2.7，需要额外安装的库有两个，一个是Beautiful Soup，（解析网页）一个是MySQLdb（连接mysql）

进入https://download.youkuaiyun.com/download/qq_34288630/10407440
下载
MySQLdb

下载号双击exe：

此时遇到问题
安装MySQL-python-1.2.4b4.win32-py2.7.exe的时候，出现python version 2.7 required,which was not found in the registry，翻译过来就是：不能再注册表中识别出来python2.7，解决方案如下：

新建register.py，用IDLE工具打开，复制以下代码进去，并且运行 ，如果显示 — Python 2.7 is now registered! 表示配置成功，如下图：
代码：

#
# 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()

然后重新安装：

就能识别出python2.7了。点击下一步安装成功就可以用了

验证是否按安装成功：
打开python.exe
输入命令：

import MySQLdb
如果不报错则安装成功
