server 出错

[zhonggedan]

windows
node：6.9.1

执行node app.js没报错，但是一访问http://localhost:3000/test/show 随便访问一个都出现下面的错误，没改动过源码

同样的问题，使用如下代码routes.js：

var service = require('./services/test');
var message = require('./services/message');
var user = require('./services/user');
module.exports = function(app){
  service.init(app);
  message.init(app);
  user.init(app);
}

可以打开localhost:3000/test/test

没有使用fs去循环require文件，并初始化routes.

这是为什么？！！
