Revision history [back]

The line from original tutorial launch-file (on the second link you gave)

<node pkg="turtle_teleop" type="turtle_teleop_joy" name="teleop"/>

tells roslaunch to start a node by running turtle_teleop_joy executable (type parameter) which is located within turtle_teleop package (pkg parameter). If you change pkg parameter on this line roslaunch will search for the executable within another package/folder, i.e. learning_joy. So, if there is no such executable (node) there, then roslaunch will issue an error.
