Make sure that you have run catkin_make inside the catkin_ws directory. If you have already done that, I suspect that you have not added your catkin_ws in your bashrc. If you haven't just run the following command:

echo "source /home/pi/catkin_ws/devel/setup.bash" >> /home/pi/.bashrc


Then close all terminals or run (on each open terminal):

source /home/pi/.bashrc
