Arduino IDE: "Error compiling for board"

Hello Everyone,

I was just working on a project, but when I finished with the code, the Arduino IDE would not let me upload it to the Arduino. The Arduino is connected to the computer, and I can see it via the Serial Monitor, but when I press the Upload or the Verify button, the IDE says: "Error compiling for board Arduino/Genuino Uno". The code itself does not have any errors, though. Does anybody know how to fix this issue?
