Node.js 找不到socketstream应用程序404

我试图用express和cors加载socketstream应用程序，这会抛出一个错误，声明404。所有项目目录在浏览器中都可用，但没有内容

var app = require('express')();
var ss = require('socketstream');
var cors = require('cors');

ss.client.define('main', {
  view : 'app.html',
  css : [],
  code : [],
  tmpl : '*'
});

app.use(cors());


app.get('/', function(req, res) {
 res.serve('main');
});

ss.start(app.listen(port));

这是浏览器中的响应

更新

app.html正在浏览器中加载，但404仅用于从app.html请求的脚本和css
