node.js和socket.io未捕获错误

我正在尝试使用ntwitter,node.js和socket.io来访问Twitter用户流.推特用户流工作正常,我可以实时获取推文.推文使用以下功能显示在控制台中.

console.log(data.text) ;

然后我想将数据推送到浏览器.这可以使用套接字完成.以下链接显示了twitetrs公共流的简单node.js客户端的示例.

现在同样不适用于我的用户流.数据在控制台中显示没有任何问题,但如果我尝试将其推送到浏览器,我会收到错误.

Error: Uncaught, unspecified 'error' event.

代码是：

var app = require('express').createServer(),
twitter = require('ntwitter'),
io = require('socket.io').listen(app);
app.listen(3000);

var twit = new twitter({
consumer_key: 'key',
consumer_secret: 'consumer secret',
access_token_key: 'token',
access_token_secret: 'token secret'
});

twit.stream('user', {track:'nodejs'}, function(stream) {
stream.on('data', function (data) {
io.sockets.emit('tweet',{
  user: data.user.screen_name,
  text: data.text
});
});
});
app.get('/', function (req, res) {
res.sendfile(__dirname + '/index.html');
});

请帮我.

处理错误可能有效：

stream.on('error', function(error) {
    console.error(error);
});
