Hi.
I'm using
Ubuntu 14.04
ROS Indigo
Gazebo2
I am quite new to ROS and Gazebo and I'm following this Tutorial link:[here](http://www.generationrobots.com/blog/en/2015/02/robotic-simulation-scenarios-with-gazebo-and-ros/).
I did everything like in the tutorial, nut when I want to use roslaunch to launch my launchfile I get the following error:
Invalid tag: Cannot load command parameter [robot_description]: command [/opt/ros/indigo/share/xacro/xacro.py
/home/myuser/catkin_ws/src/mybot_description/urdf/mybot.xacro] returned with code [1].
Param xml is
The traceback for the exception was written to the log file
When I enter
rosrun xacro xacro.py /home/myuser/catkin_ws/src/mybot_description/urdf/mybot.xacro
I get
