I'm using gazebo 2.2.5 version with Ubuntu TRUSTY. I would like to launch the turtlebot_world.launch file in order to operate a turtlebot with the kobuki_keyop package in an empty world. While launching the file, I get this error: Invalid <arg> tag: environment variable 'TURTLEBOT_GAZEBO_WORLD_FILE' is not set.

Arg xml is <arg default="$(env TURTLEBOT_GAZEBO_WORLD_FILE)" name="world_file"/> The traceback for the exception was written to the log file

How can I set the TURTLEBOT_GAZEBO_WORLD_FILE parameter so that the command will work?

Seeking forward for ones help

Have you installed ros-indigo-turtlebot-gazebo?

It did work after opening the terminal again. Maybe because the environment variable wasn't loaded.

It asks for a world file, so give it a world file. Something like

roslaunch turtlebot_gazebo turtlebot_world.launch world_file:=/opt/ros/indigo/share/turtlebot_gazebo/worlds/playground.world

This MAY work for now, but you should really stick to the way the package developers support. See the link in my answer.

Worked for me in kinetic:

export TURTLEBOT_GAZEBO_WORLD_FILE=/opt/ros/kinetic/share/turtlebot_gazebo/worlds/playground.world
roslaunch turtlebot_gazebo turtlebot_world.launch

Turtlebot utilizes environment variables that are set by env hook. See this tutorial.

I got the exact same error but I realized that it was because I had a $roscore running at the time that I was entering the roslaunch command. You should close all terminals if possible and then run the simulation in a new one.
