The correct solution is sudo killall node and re run node file.js

The following worked for me:
Go to task manager and close all nodejs processes, then close the terminal and create a new one, and that's it!!!!

OK, it works, but it's tiring to have to change it every time I run the program

Thank u so much. But I still cant get why is it that when I search for this port it shows my old code. I should be able to update it every time i put node js server.js on the terminal.

Other solution is: ps -aux | grep 'node index.js', then kill -9 PID
