nodemon 将运行app.js文件
app.js代码如下
const express = require('express');
const app = express();
app.get('/', (req, res) => {
res.send('hello world')
})
app.listen(3000,()=>{console.log("Server running at http://127.0.0.1:3000/");})
nodemon 第一次启动正常
[nodemon] 2.0.12
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node app.js`
Server running at http://127.0.0.1:3000/
然后直接ctrl+s保存,报如下错误
[nodemon] restarting due to changes...

尝试过后发现是这一块代码的问题
app.listen(3000,()=>{console.log("Server running at http://127.0.0.1:3000/");})
