ImportError: No module named MySQLdb 该错误是源于我们没有安装Python连接MySQL所需的MySQLdb库而引起。 MySQL是最流行的开源数据库之一，但在Python标准库中并没有集成MySQL接口程序，MySQLdb是一个第三方包，需独立下载并安装。Python连接MySQL的关键之处在于设置数据库连接，在连接成功之后，其实不管后端是何种数据库，对DB-API对象的属性和方法进行操作都是一样的。 下载地址：http://sourceforge.net/projects/mysql-python/ 对于Linux来说，有多重包管理系统和安装机制。如果使用的是包含某种包管理器的Linux，那么可以很轻松的安装Python MySQLdb库。 Linux Fedora, CentOS系统：yum install MySQL-python Linux Ubuntu操作系统：apt-get install python-mysqldb 下面的代码演示了如何创建一个表，插入和访问数据等简单操作： #!/usr/bin/env python import MySQLdb 来源： oschina 链接： https://my.oschina.net/u/942301/blog/333104
