引用错误:未定义猫鼬 - Node.js

Question

我是一名学生，作为作业的一部分，我正在开发一个连接到openweatherapp website并检索数据的天气应用程序。从命令提示符作为nodemon index.js执行时，我收到以下错误。

引用错误： 未定义猫鼬 在对象。(C：\Users\anand\Desktop\Sem 4\web apps\Assignment 3\2298917_193294482_708854\708854\app\index.js：7：18(

索引.js的代码是

var http = require('http');
var express = require('express')
var app = express();
app.set('view engine', 'ejs');
var city = 'Las Vegas';
mongoose.connect('mongodb://prettyprinted:[e-mail]:53879/express_weather')
var citySchema = new mongoose.Schema({
name: String
});

var request = require('request');
//http.createServer(function (request, response) {
//var request = require('request');
var url = 'http://api.openweathermap.org/data/2.5/weather?q=London&appid=7970f50f59ddccaf607b8a4890574039';
app.get('/', function (req,res) {
request(url, function (error, response, body) {
weather_json = JSON.parse(body);
console.log(weather_json);
var weather = {
city: city,
//temperture: Math.round(weather_json.main.temp),
Descrip: weather_json.weather[0].description,
icon: weather_json.weather[0].icon
};
var weather_dat = {weather : weather};
res.render('weather', weather_dat);
});
//res.render('index')
});
app.listen(11223);

请指教。

是的，您需要添加指令

var mongoose = require('mongoose')

一定要做npm install mongoose
