Error when I try to launch RosBridge server

When I just run the first command of this course “roslaunch course_web_dev_ros web.launch” in terminal 1, I get the following error:

“[web.launch] is neither a launch file in package [course_web_dev_ros] nor is [course_web_dev_ros] a launch file name
The traceback for the exception was written to the log fil[/size][/size][/size][/size]e”

Please advise.
