Question

我正在学习教程并尝试连接到mongodb，我有两个文件第一个是具有以下代码的server.js

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');

const app = express();

//body parser middleware
app.use(bodyParser.json());

//DB config

const db = require('./config/keys').mongoURI;

//connect to mongo
mongoose
  .connect(db,{ useNewUrlParser: true })
  .then(()=>console.log('Connected to mongodb...'))
  .catch(err=>console.log(err));

const port = process.env.PORT || 5000;

app.listen(port,()=>console.log(`server connected on port ${port}`));

第二个是配置文件

module.exports = {
    mongoURI:'mongodb+srv://denis:password@shoppingapp-wmnbw.mongodb.net/shopping?retryWrites=true&w=majority'
}

我想要实现的是在控制台connected to mongodb...上显示相反，我收到此错误消息

server connected on port 5000

我试图更改驱动程序版本，但仍然出现错误，我在哪里出错？
