creation of service server failed for rosserial_tivac_tutorials/rgb_srv #2

Hello,

When I run the rgb_srv example, I get the following error from serial_node.py

I am on Ubuntu 18 with ROS melodic, but I also tested it with Ubuntu 16.04 with ROS kinetic, and for some reason it can not create the service server on ros side.

can@rose:~$ rosrun rosserial_python serial_node.py _port:=/dev/ttyACM0 _baud:=57600 [INFO] [1542288687.044028]: ROS Serial Python Node [INFO] [1542288687.047171]: Connecting to /dev/ttyACM0 at 57600 baud [INFO] [1542288689.151538]: Requesting topics...

This error too happens because the message files are not in path.

cd ~/catkin_ws source devel/setup.bash

solves the problem.
