Gazebo sim not running because installed netifaces module not found

I'm trying to run this Gazebo simulation: https://github.com/disaster-robotics-proalertas/usv_sim_lsa

I've followed along and installed ROS kinetic on my Ubuntu 16.04. But I keep getting an error for netifaces module not found, even though I've repeatedly installed it and can import netifaces when I launch python in the terminal.

I've tried installing python-netifaces and using

rosdep install --from-paths src --ignore-src --rosdistro groovy -y

it shows all required rosdeps are installed.

Just trying to run this line: roslaunch usv_sim airboat_scenario1.launch parse:=true

Here's the error I keep getting:

rameezs:~/catkin_ws$ roslaunch usv_sim airboat_scenario1.launch parse:=true ... logging to /home/rameezs/.ros/log/5cbbdbb0-c28f-11e9-bea5-88b111c4685a/roslaunch-thinkram-16846.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

I believe it might a python path related issues. when you do such binary installations, in general those packages get installed in dist-package file of the respective python either python 2.7 or python 3. And ros-kinetic uses python 2.7 for its basic commands such as roslib and rospy. So please try to check whether the installed netifaces are in the same pythonpath, if not try to export python path before launching the file.

Als please try to check the python path from the terminal you are launching your file, that way you will know which python paths are imported, if python3 path is not imported, please try to export that path aswell.
