ubuntu-安装了mysqlconector后然无法引入

我在ubuntu14.4上面操作，python2.7，mysql5.5 ，用了virtualenv，
当我在虚拟环境外安装好mysql-connector-python_2.0.4-1ubuntu14.04_all.deb后可以正常使用，

 think@think-Inspiron-N4050:~/download$ sudo dpkg -i mysql-connector-python_2.0.4-1ubuntu14.04_all.deb [sudo] password for think: Selecting previously unselected package mysql-connector-python.(reading databse ...)Preparing to unpack mysql-connector-python_2.0.4-1ubuntu14.04_all.deb ...Unpacking mysql-connector-python (2.0.4-1ubuntu14.04) ...setting mysql-connector-python (2.0.4-1ubuntu14.04) ...think@think-Inspiron-N4050:~/download$ python Python 2.7.6 (default, Jun 22 2015, 18:00:18) [GCC 4.8.2] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> import mysql.connector>>> exit()

我需要在virtualenv环境下使用，于是我又在venv环境里安装了一个，安装正常，但是无法引入

请各位老师指点一下，谢谢
