node.js express应用程序可以'；找不到jade view，404消息响应

对于我的应用程序，我使用node.js作为后端，使用Express作为框架。我将Netbeans用作IDE，并获得以下输出

Not Found
404

Error: Not Found

at router (/home/ingeborg/netbeans/GML/node_modules/express/lib/router/index.js:47:12)

我有以下数据设置：

- node-modules
- public
    - fonts
    - images
    - javascripts 
    - stylesheets
        stylesheets.less
        stylesheet.css
    - routes
        index.js
        news.js
        users.js
    - views
        index.jade
        error.jade
        news.jade
        layout.jade
    Gruntfile.js
    app.js
    gulpfile.js
    package.json

app.js看起来像这样

var news  = require('./routes/news');
var index = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
...
app.use('/', index);
app.use('/index', index);
app.use('/news', news);
app.use('/users', users);

这是我的索引

h3 
  a(href="news") link

这是我的消息

h3 test

路由是通过路由文件实现的。 index.js

var express = require('express');
var router = express.Router();

/* GET home page. */
router.get('/', function(req, res, next) {
    res.render('index');
});

router.get('/index', function(req, res, next) {
    res.render('index');
});
module.exports = router;

news.js路由器文件是

var express = require('express');
var router = express.Router();

/* GET home page. */
router.get('news', function(req, res, next) {
    res.render('news');
});
module.exports = router;        

以下情况不适用：

• 链接“/”和“索引”上的路由按需要工作
• “/news”或“news”（在rounting、app.js和view文件中测试）上的路由不可用。我不知道为什么路由不起作用。我希望我没有忘记某事

Thx，

新闻路线文件丢失。在那里，你必须把你的玉石呈现出来

var news  = require('./routes/news');

在app.js中？这是第一行还是它属于另一个位置？您在app.js上指定对所有/news路由使用文件/routes/news.js，但在数据设置列表中，routes文件夹中缺少news.js文件。我刚才看到的第二件事是，您将两次路由到/news/news，一次是在app.js中通过app.use（'/news'，news）；第二次是通过news.js文件router.get（'news'，function（req，res，next）…sou，您可以尝试访问或将router.get（'news'）…更改为router.get（“/”…在您的news.js.done.404中。作为比较，请查看索引视图的路由。路由文件中有相同的code.news.js。这是我的错误。它是安装的一部分。在app.js中？它是第一行还是属于其他位置？您在app.js中指定对所有/news路由使用文件/routes/news.js，但在您的d中ata安装列表routes文件夹中缺少news.js文件。我刚才看到的第二件事是，您两次路由到/news/news，一次路由到app.js over app.use（'/news'，news）；第二次路由到news.js文件router.get（'news'，function（req，res，next）…sou您可以尝试访问或更改路由器。get（'news'，to router.get（“/”…在您的news.js.done.404中。作为比较，请查看索引视图的路由。路由文件中有相同的code.news.js。这是我的错误。它是设置的一部分。您使用了哪个IDE？我使用升华文本。上面的示例是由express cli生成器创建的

express--view=jade myapp

现在就知道了。下面的“/”在我删除“/news”just to“/.Thx”后，jade文件中缺少“/”。谢谢你的帮助！你使用了哪一个IDE？我使用了升华文本。上面的示例是由express cli生成器创建的

express--view=jade myapp

立即获得的。在我删除“/news”just to“/.Thx alot后，jade文件中缺少“/”。谢谢你的帮助！
