ImportError: No module named mavros_msgs.msg

Im using ros kinetic and Ubuntu 16.04

Im trying to do run this project but not running inside a docker container. I had copied the whole gym file from container to my desktop and try to run outside the docker container.

After i had done

user@user-HP-Pavilion-15-Notebook-PC:~/gym/gym-gazebo/gym_gazebo/envs/installation$ bash turtlebot_setup.bash
user@user-HP-Pavilion-15-Notebook-PC:~/gym/gym-gazebo/examples/scripts_turtlebot$ python circuit2_turtlebot_lidar_qlearn.py

I get this

/usr/lib/python2.7/dist-packages/skimage/viewer/qt/__init__.py:18: UserWarning: Could not import PyQt4: ImageViewer not available!
  warnings.warn("Could not import PyQt4: ImageViewer not available!")

And this is my turtlebot_setup.bash

#!/bin/bash

#copy altered urdf model
cp -r ../assets/urdf/kobuki_urdf/urdf/ catkin_ws/src/kobuki/kobuki_description

#copy laser mesh file
cp ../assets/meshes/lidar_lite_v2_withRay.dae catkin_ws/src/kobuki/kobuki_description/meshes

exec bash # reload bash

What should I do to solve this? and How do I properly install the package?

Check To See If U Have The Msg In Your Env-Path With rosmsg list.

if You Don't Have It There Then It's Your Path Problem Try sourcing The setup.bash Of Main ROS folder(or if U compiled it from source setup.bash from Your Workspace)

EDIT 1

you can install Mavros (and Mavros_msgs) using apt install ros-kinetic-mavros ros-kinetic-mavros-msgs
