Hi,everyone. I install ros-by-exanple-indigo code on my computer.And I prepare to test fake robot simulator.However,Once I run the .launch file there will be a mistake in rviz.See follow.

run command:



roslaunch rbx1_bringup fake_turtlebot.launch


rosrun rviz rviz -d 'rospack find rbx1_nav' /sim.rviz

then there's a mistake in rviz,

Global Status :error fixed frame :fixed frame [map] do not exist

(the node works fine, as I publish the command to it and it can show it moves from the command line screen. So there should be some problems with the rviz I guess.)

What direction should I go?

Self-answering again...: Found this tool is quite useful: roswtf. It tells me that my ROS_HOSTNAME is not set correctly. I just changed my IP and my hostname to this machine, so that's the reason.

Suggestion would be:

change your IP address in /etc/hosts and /etc/network/interfaces. And make sure in the ~/.bashrc your IP address is correct. For a single machine, suggest your IP address is set to
