使用 nodemon 启动服务器时出错

Question

So i am running an simple express web app, i install nodemon modules so i dont have to restart the server, but apparently there is an error

This is the error

events.js:141
  throw er; // Unhandled 'error' event

I installed nodemon through npm and i installed it globally (into appdata/npm) My server code is quite simple, here:

const EXPR = require('express');

// set up express app
const APP = EXPR();

// Handle get request
APP.get('/', function(req, res){
   console.log('GET request');
   res.send({"name":"Yoshi"});
});
// listen for request
APP.listen(process.env.port || 2000, function(){
   console.log("Now listening for request !");
);

Can anyone help me please, i really want this feature as it is very convenient for nodejs, thanks a lot !

Answer 1

If you are using windows make sure to set

%SystemRoot%\system32;  /// this is c:\Windows\system32

in environment path.

Answer 2

Add the following to your package.json

{
  "scripts": {
    "start": "nodemon index.js"
  }
}

Then npm start should be enough to run your application. You should also consider putting nodemon as a dev dependency.

Answer 3

Open the windows powershell and add this line.

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
