按照github上的quick start一步一步下来，npm start 启动server， 但app.js貌似没有监听任何端口，但是server启动了？通过浏览器访问不了页面，是这样吗？
究竟是哪里有问题？
创建方法就是：
$ express /tmp/foo && cd /tmp/foo
启动服务器是:
$ npm install
$ npm start

正如一楼说的，默认的是3000端口，写在bin/www里，但问题是这里明明debug出了文本，为什么终端窗口里看不到？
var server = app.listen(app.get('port'), function() {
debug('Express server listening on port ' + server.address().port);
});

Looking at the project generated by express,
/bin/wwwrequired the https://github.com/visionmedia/debug module.You can see all debug information like this:
Of course there is also the sentence you expect to see: Express server listening on port 3000
