Neither rospack find nor roscd can find ca_driver
Neither rospack find nor roscd can find ca_driver, I have tried installing on two different computer using exact instruction given on git page and also tried adding the ROS Path, passing full path to roslaunch but it says:
" [create_2.launch] is neither a launch file in package [ca_driver] nor is [ca_driver] a launch file name The traceback for the exception was written to the log file"
Please help.
