http://howtonode.org/express-mongodb 我尝试运行此示例，当我尝试运行节点app.js时，我收到了一个ReferenceError。

它是index.jade文件中的内容，但我似乎无法弄清楚它出错的地方。

编辑添加：这是index.jade文件：

block content
  h1= title
  #articles
    - each article in articles
      div.article
        div.created_at= article.created_at
        div.title 
            a(href="/blog/"+article._id.toHexString())!= article.title
        div.body= article.body

        extends layout

这里是索引页面的app.get：

app.get('/', function(req, res){
    articleProvider.findAll( function(error,docs){
        res.render('index.jade', { locals: {
            title: 'Blog',
            articles:docs
            }
        });
    })
});

它在功能中传递了标题，所以我真的不确定问题是什么。

好的，所以我认为快递render API已经发生了变化。尝试删除“locals”属性并直接传递数据：

app.get('/', function(req, res){
    articleProvider.findAll( function(error,docs){
        res.render('index.jade', {
            title: 'Blog',
            articles:docs
        });
    });
});
