I am new to ros and first using it for project while i was following this previous project link https://github.com/hans-robot/elfin_robot/blob/kinetic-devel/README_english.md

i got error after the command

roslaunch elfin3_moveit_config moveit_planning_execution.launch

in Usage with Gazebo Simulation part i got this error

[moveit_planning_execution.launch] is neither a launch file in package [elfin3_moveit_config] nor is [elfin3_moveit_config] a launch file name
The traceback for the exception was written to the log file

i dont know will it help or not I have checked that file "moveitplanningexecution.launch" path is catkinws->src->elfinrobot->elfin3moveitconfig->[moveitplanningexecution.launch

i also run next 2-3 commands but got the same type of error how to resolve this
