Ros Environment in root












1















I have a ros (kinetic) environment set up on a raspberry pi 3 and am trying to get ros to execute upon startup via a simple bash script which calls roslaunch. Ros works in the user domain but fails when called from root.
Here is my launch_ros.sh script:



#!/bin/bash
source /home/pi/ros_catkin_ws/devel/setup.bash
export PYTHONPATH=/opt/ros/kinetic/lib/python2.7/dist-packages
roslaunch my_pkg pkg_launch.launch


When I run sudo /home/pi/Desktop/ros_launch.sh the roscore crashes with



ERROR: cannot launch node of type [rosout/rosout]: can't locate node
[rosout] in package [rosout] failed to start core service [/rosout]
The traceback for the exception was written to the log file


But, if I comment out



source /home/pi/ros_catkin_ws/devel/setup.bash


and execute /home/pi/Desktop/ros_launch.sh, ros works fine.



Also worthy of noting is if I leave the above source line uncommented when running in the user domain I get the same error as I do in the root. I think this might be pointing me to the solution but I am still very new to ros.
Has anyone come across this issue and found a solution?

          In order to run a node as root after changing your shell to root using commands like sudo -i, You can source your current bash profile thats located inside your normal user .bashrc and use it inside root shell.
