javascript – 在基本的Express.js应用程序中“无法查找视图”

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看起来如下：

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,文件的权限还可以.
任何想法为什么快递找不到我的index.jade文件？

解决方法:

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index.jade放在名为views的文件夹中.

并确保您的node_modules文件夹中有jade
