Gazebo_ros module missing

So basically I'm trying to run a model on gazebo and since I'm very new to Ros and gazebo I have no idea why I'm having this problem.

When I run

roslaunch mybot_gazebo mybot_world.launch

It will give me the problem above: ImportError: no module named gazebo_ros

I'm running ubuntu 14.04 and ros-jade

Thanks for the help and ask anything if i've not provided all the info
