[start_logger_example.launch] is neither a launch file in package [logger_example_pkg] nor is [logger_example_pkg] a launch file name
The traceback for the exception was written to the log file
It seems like there is no such package available. Can someone tell me if I am doing something wrong? Thanks.
You did not create the start_logger_example.launch. If that is the case, just follow the instructions of the lesson Unit and create it. Remember that the package has to be created inside the catkin_ws/src directory. Also remember that you cannot create packages by copy/pasting directory of another package. You have to use catkin_create_pkg.
You create it but you misspelled it. This is very common mistake. Check your name for the package and for the launch file and modify it accordingly.
