首先需要清楚，MySQL-python这个模块其实是封装了MySQL C驱动的Python驱动，所以它是需要依赖于mysql connector C！！！

在安装MySQL-python模块时，如果电脑中没有事先安装mysql connector C，请移步至mysql connector c，下载mysql的C语言连接器。打开界面可以看到有32位的和64位的：



这个时候选择下载可不是根据你的操作系统来下载的，而是根据刚刚安装MySQL-python的报错信息来下载的，从报错信息里面可以看到，在查询config_win.h文件是从C:\Program Files (x86)\MySQL\MySQL Connector C 6.0.2\include，目录下查找的，32位的软件一般都会装在这个目录（Program Files (x86)）下，一般64位的软件默认直接装在Program Files目录下，所以直接下载32位6.0.2的版本安装的即可，安装完成后，再次尝试重新安装MySQL-python模块。

一般情况下，就可以安装成功，并且可以导入使用了



可以看到没有报错，可以正确导入，接下来我们就可以正常使用这个模块了。

凡事都有万一，如果你很不幸，出现了跟我在另一台电脑安装时一样的错误，这我就无能为力了，错误信息如下：

给我的感觉像是编译链接的问题，能力有限，不知道怎么解决！！！

不过凡事都有一线生机呀，网上有一个mysql-python的安装程序，需要的可以直接下载安装即可：下载网页，多亏了网上一个哥们提供了连接，不然都不知道怎么才好，总不能重做系统吧。。。。
