错误：无法在视图目录中查找视图“students/addEdit.hbs”

Question

我将使用 MongoDB 在 NodeJS 中构建一个应用程序。 但是我在数据库中插入数据时遇到问题 请帮助我为什么会发生此错误。

Error: Failed to lookup view "students/addEdit.hbs" in views directory "D:\Projects\NodeJS\views"

下面是我的 server.js 代码

require('./models/db');

const express=require('express');
const path=require('path');
const exphbs=require('express-handlebars');
const bodyparser=require('body-parser');

const studentController=require('./controllers/studentController');
//const stdController=require('/controllers/stdController')

var app=express();
app.use(bodyparser.urlencoded({
    extended:true
}))

app.use(bodyparser.json());
app.set('views', path.join(__dirname, '/views'));
app.engine('hbs', exphbs({extname:'hbs', defaultLayout:'mainLayout', layoutsDir: __dirname+'/views/layouts/'}));
app.set('viee engine', 'hbs');

app.listen(4000, ()=>{
    console.log('Express server started at port:4000');

})
app.use('/student', studentController);
