    The cause: There are 2 reasons of this error:

    1. Running node in background

    pkill -f node

    It worked in Mac OS  but did not work in Microsoft.

    2. Server.js and package.json are not in same folder .

    Solution: You need to check package.json by doing:

    "scripts": {
    "test": "echo "Error: no test specified" && exit 1",
     "start": "nodemon Server.js"
 }

  2. This is due to all the background server processes. You can simply stop them by closing the terminal.

    Quick tip

    FOR LINUX

    Run this command on your terminal to kill them all: 

    pkill -f node

    Then, restart nodemon.

    FOR Windows 

     1. Go to the task manager
 2. Then look for Node.js: Server-side JavaScript
 3. Then right click on it and End task from the processes.

    Next, restart the server. It should work perfectly.
