javascript - 基本 Express.js 应用程序中的 "Failed to lookup view"

Question

我正在尝试学习 Express.js，所以我创建了简单的 Express 应用程序。 app.js 如下所示:

var express = require('express'); 
var app = express();

app.configure(function(){
    app.set('view engine', 'jade'); 
    app.set('views', __dirname);
});

app.get('/', function(req, res){ 
    res.render("index");
});

app.listen(8080);

我的文件夹结构如下:

但是，当我将浏览器指向 http://localhost:8080 时，我得到以下输出:

Error: Failed to lookup view "index"

我已经检查过，文件的权限没有问题。为什么 express 找不到我的 index.jade 文件有什么想法吗？

Answer 1

试试这段代码:

var express = require('express');
var app = express();

app.use(express.logger('dev'))

app.set('views', __dirname+'/views');
app.set('view engine', 'jade');

app.get('/', function(req, res){
    res.render("index");
});

app.listen(8080);

然后将您的 index.jade 放入名为 views 的文件夹中。

并确保您的 node_modules 文件夹中有 jade
