start.js中require就直接报错了，不是报 require 没有定义，而是指着require的 r 没有定义。

(function (exports, require, module, __filename, __dirname) { require('babel-core/register')({

                                                              ^

ReferenceError: r is not defined

start.js的代码如下：

require('babel-core/register')({
'presets': [
'stage-3',
'latest-node'
],
'plugins': [
'transform-decorators-legacy',
['module-alias', [
{ 'src': r('./server'), 'expose': '~'},
{ 'src': r('./server/database'), 'expose': 'database'}
]
]
]
})

require('babel-polyfill')
require('./server')
