Examples 6.8 in unit 6


Could anyone help that why this error occurred?

I can’t figure out the error without the command that caused it. Was it catkin_make? If so, make sure that your packages are built correctly and make sure the workspace compiles correctly before you source or do anything with catkin_ws
