node.js - 无法在 View 目录中查找 View "index"| express | HBS 代替handlebars.js

Question

view-engine

我已经安装了hbs而不是handlebar来进行动态模板，现在我陷入了这个问题。

Error: Failed to lookup view "index" in views directory "/home/trijay/Desktop/NodeJs/web-server/src/views"
    at Function.render (/home/trijay/Desktop/NodeJs/web-server/node_modules/express/lib/application.js:580:17)

下面是我的 app.js 代码，我还安装了 hbs、express 库。任何帮助将不胜感激

//app.js

const express = require('express')
const path = require('path')


const publicPath = path.join(__dirname, '../public')   //for accessing comeplete file

const app = express()   //express being initialised


app.use(express.static(publicPath))
app.set('view engine', 'hbs')    //use to set handle bars. we need to provide key value pair

app.get('', (req, res) => {
    res.render('index')             //need to provide the hbs file name which you will find in view
})


app.get('/weather', (req, res) => {
    res.send({
        latitude: -57.89,
        longitude: 78.42,
        location : 'New Delhi'
    })

})

app.listen(3000, () => {
    console.log('Server Started on port 3000')
})

将 views 目录添加到引擎选项中:

app.set('view engine', 'hbs') 
app.set('views', path.join(__dirname, '../views'));

正如您在错误消息中看到的:

Error: Failed to lookup view "index" in views directory "/home/trijay/Desktop/NodeJs/web-server/src/views"

res.render('index') 指向 src 目录中的某个位置。
