I've got this message when I run roslaunch my_gmapping gmapping.launch

RLException: [gmapping.launch] is neither a launch file in package [my_gmapping] nor is [my_gmapping] a launch file name
The traceback for the exception was written to the log file

That code exists in this path

Home/catkin_ws/src/my_gmapping/launch

Source the setup.bash from your terminal or through your bashrc and run rospack profile:

echo "source $HOME/catkin_ws/devel/setup.bash" >> $HOME/.bashrc   
source $HOME/.bashrc   
rospack profile
