2015-01-21 01:53:45 -0500	asked a question	Invalid <param> tag Error? when I run `roslaunch rbx1_bringup fake_turtlebot.launch`, there is something wrong like this: `Invalid <param> tag: Cannot load command parameter [robot_description]: command [/opt/ros/hydro/share/xacro/xacro.py '/home/snoopy/myspace/src/turtlebot_description/urdf/turtlebot.urdf.xacro'] returned with code [1].` Param xml is `<param command="$(arg urdf_file)" name="robot_description"/>` I've searched a lot, but still don't know how to solve this.
