Yarn Start does not work for me in the terminal

I am attempting to View my Local host Browser using the “Yarn Start” In the Terminal, however when i try to open it i get an error that says “Compiled with problems:X

ERROR in ./src/App.js 6:0-56

Module not found: Error: Can’t resolve ‘./components/DirectoryComponent’ in ‘/Users/keithquinney/Desktop/NucampFolder/3-React/nucampsite/src'”

Any ideas as to what the problem could be , as i retraced my steps to see if i was missing something including looking at my fellow classmates code to compare and i don’t screenshot seem to find the source of the problem. ** Please see the Screenshot attached** Thank you
