问题描述：由于之前使用python3.2.2版本，使用很多第三方库不方便，就将python重装为python2.7.4版本，当时装的MySQLdb也忘了，现在到使用时才想起要重装MySQLdb，就用pip install mysql-python直接安装，但是报错，如下图
环境工具：Win7(32bit) Python2.7.4
解决过程：看到一篇英文技术文章，部分摘录如下
Installing mysql module for python
I rate this mission as : impossible for the everyday developer on windows.
Here are several of the problems I got along the way :
_mysql.c:34:24: fatal error: config-win.h: No such file or directory
serverKey = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, options['registry_key'])
WindowsError: [Error 2] The system cannot find the file specified
error: Unable to find vcvarsall.bat
Save yourself the headache -
Search for a "download compiled python 2.7 mysql for windows"
change the query to your python version.
Do not stop until you find a file named
"MySQL-python-1.2.3.win32-py2.7.exe"
again - version might be different.
Do not go on the mission of installing it by yourself, it is simply a nightmare.
意思就是说下载已经针对win7 32编译好的MySQLdb来安装
想起来，之前的MySQLdb也不是通过pip安装的，只好去下载一个MySQL-python-1.2.3.win32-py2.7.exe来安装，很快OK。
