How to fix this problem ? in ubuntu 14.04 (hector_exploration_node]
I cloned source code of hector navigation to my share folder. Then I compiled all packets with rosmake.
When I want to run "roslaunch hectorexplorationnode exploration_planner.launch" I get error which is :
"ERROR: cannot launch node of type [hectorexplorationnode/explorationplannernode]: can't locate node [explorationplannernode] in package [hectorexplorationnode]"
My ros version is "indigo".
What is wrong? How can i fix it ?

Try rospack find hector_exploration_node. If that gives error, then you need to export the path

it doesn't give error. returns "/opt/ros/indigo/share/hector_exploration_node"
