So i readed about this error and i understood that i need to make config file somewhere with some script in it but that's the problem i don't know where do i make it in this situation

Answer 1

This error means you already have something running on port 8000 (probably another instance of your app). Close or kill that process and restart.

PS If you are on a UNIX-based system you can run lsof -i 9000 and then kill process by name.
