I am following this This tutorial. I installed joint_state_publisher and urdf tutorials. the following command

$ roslaunch urdf_tutorial display.launch model:=urdf/01-myfirst.urdf

is giving following error

Invalid <param> tag: Cannot load command parameter [robot_description]: command [/opt/ros/indigo/share/xacro/ urdf/01-myfirst.urdf] returned with code [1]. 
Param xml is <param command="$(find xacro)/ $(arg model)" name="robot_description"/>
The traceback for the exception was written to the log file

So how to solve this error?
