This error message indicates that the port number 3000 is already in use by another process on your computer.
To fix this error, you can try the following steps:
1. Stop the process that is using port 3000: You can use the command `sudo lsof -i :3000` to find the process ID (PID) that is using port 3000, and then use the command `kill <PID>` to stop that process.
2. Change the port number: If you cannot stop the process that is using port 3000, you can try changing the port number of your application to a different value. This can be done by modifying the code of your application or by passing a different port number as an argument when starting your application.
3. Wait for some time: Sometimes, the process that was using port 3000 may take some time to release the port after it has stopped. In this case, you can wait for a few minutes and try running your application again.
