## 1、下载MySQLdb
[去官网](http://pypi.python.org/pypi/MySQL-python/)
下载对应的编译好的版本（现在官网最新版本为1.2.5）：
MySQL-python-1.2.5.win32-py2.7.exe
得到1MB的安装文件
MySQL-python-1.2.5.win32-py2.7.exe
## 2、安装
以上版本目前只支持到python2.7，在安装MySQLdb之前确定你已经在电脑上安装了python27。
双击安装：
然后点下一步出现：
我确实已经安装了python 2.7
究其原因是因为此x86的exe，是不支持我的win7 x64。
## 3、源码安装
[下载源码] (https://pypi.python.org/pypi/MySQL-python/1.2.5)
然后再去解压和安装，结果果然出现错误：

然后再参考：
Windows下安装MySQLdb遇到的问题及解决方法
所说的：
1）问题 ： _mysql.c(34) : fatal error C1083: Cannot open include file: ‘config-win.h’: No such file or directory
error: command ‘”C:/Program Files/Microsoft Visual Studio 9.0/VC/BIN/cl.exe”‘ failed with exit status 2
原因 ：原因是安装MySQL的时候没有安装C语言库。
解决 ：重新运行MySQL的安装程序，选择Modify，把“C Include Files / Lib Files”勾选上，并安装。
