I operate on ubuntu14.4, python2.7, mysql5.5, using virtualenv,
When I have installed a mysql-connector-python_2.0.4-1ubuntu14.04_all.deb outside of the virtual environment,

 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()

I need to use it in the virtualenv environment, so I installed another one in the venv environment. the installation is normal, but it cannot be introduced.
