在收到与 deepstream + express 的握手响应之前连接关闭

Question

我想用 express 测试 deepstream。找到这个模板 https://github.com/deepstreamIO/ds-tutorial-express

但是当我运行它时，我收到错误消息：连接在收到握手响应前关闭

为什么这个例子不起作用？

Server.js

var Deepstream = require( 'deepstream.io' );
var http = require( 'http' );
var express = require( 'express' );
var deepstream = new Deepstream();

var app = express();
var server = http.createServer(app);

app.get('/hello', function ( req, res ) {
  res.send( 'Hello to you too!' );
})

deepstream.set( 'httpServer', server );
deepstream.start();

server.listen( 6020, function(){
    console.log( 'HTTP server listening on 6020' );
});

        });

在客户端，能不能切换到这个CDNlink

<script src="https://cdnjs.cloudflare.com/ajax/libs/deepstream.io-client-js/1.1.1/deepstream.js"></script>

rawgit 指向已经是 2.0 且与 1.x 服务器不兼容的 master 分支
