為什么我的代碼執行錯誤？
var EventEmitter = require('events'.EventEmitter)
var life = new EventEmitter()
//addEventListener
life.on('qiu', function(who){
console.log('gei ' + who + ' daoshui')
})
life.emit('qiu ', 'nan')

你第一行的口號打錯地方了
你的：var EventEmitter = require('events'.EventEmitter)
正確：var EventEmitter = require('events').EventEmitter
