Revision history [back]

Slightly different error, but this might help someone who stumbled upon the same problem later: When you get

ERROR: cannot launch node of type [path_to_file] package_path
ROS path [0]=/opt/ros/...
...

triple check your launch file. In my case I had written my launch file as:

<node name="talker" pkg="$(find beginner_tutorials)" type="talker"/> instead of: <node name="talker" pkg="beginner_tutorials" type="talker"/>

So make sure you don't include the find tag.
