Error: Cannot locate node of type!

[AleVera04]

I'm trying to run Hector_Slam and RPlidar, RPlidar works fine and launches fine but whenever I try to launch tutorial launch from Hector slam it gives me this error:

process[rviz-1]: started with pid [27650]
ERROR: cannot launch node of type [hector_mapping/hector_mapping]: Cannot locate node of type [hector_mapping] in package [hector_mapping]. Make sure file exists in package path and permission is set to executable (chmod +x)
process[base_to_laser_broadcaster-3]: started with pid [27651]
ERROR: cannot launch node of type [hector_trajectory_server/hector_trajectory_server]: Cannot locate node of type [hector_trajectory_server] in package [hector_trajectory_server]. Make sure file exists in package path and permission is set to executable (chmod +x)
ERROR: cannot launch node of type [hector_geotiff/geotiff_node]: Cannot locate node of type [geotiff_node] in package [hector_geotiff]. Make sure file exists in package path and permission is set to executable (chmod +x)

I'm not sure what the problem is but here is the rest of the compile list when i launch it to see if there's anything useful:

you should try to catkin_make again after importing the git it should help the problem
