在基本的Express.js应用程序中“查找视图失败”

我试图学习Express.js，所以我创build了简单的快速应用程序。 app.js看起来如下所示：

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所示：

但是，当我的浏览器指向http://localhost:8080我得到以下输出：

 Error: Failed to lookup view "index" at Function.app.render (/Users/kuba/Documents/ws_javascript/express_spike/node_modules/express/lib/application.js:492:17) at ServerResponse.res.render (/Users/kuba/Documents/ws_javascript/express_spike/node_modules/express/lib/response.js:721:7) at /Users/kuba/Documents/ws_javascript/express_spike/app.js:10:6 at callbacks (/Users/kuba/Documents/ws_javascript/express_spike/node_modules/express/lib/router/index.js:161:37) at param (/Users/kuba/Documents/ws_javascript/express_spike/node_modules/express/lib/router/index.js:135:11) at pass (/Users/kuba/Documents/ws_javascript/express_spike/node_modules/express/lib/router/index.js:142:5) at Router._dispatch (/Users/kuba/Documents/ws_javascript/express_spike/node_modules/express/lib/router/index.js:170:5) at Object.router (/Users/kuba/Documents/ws_javascript/express_spike/node_modules/express/lib/router/index.js:33:10) at next (/Users/kuba/Documents/ws_javascript/express_spike/node_modules/express/node_modules/connect/lib/proto.js:199:15) at Object.expressInit [as handle] (/Users/kuba/Documents/ws_javascript/express_spike/node_modules/express/lib/middleware.js:31:5) 

我已经检查过，文件的权限是可以的。 任何想法为什么expression无法find我的index.jade文件？

Answer 1

试试这个代码：

 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); 

然后把你的index.jade一个名为views的文件夹中。

并确保你有你的node_modules文件夹中的jade
