react native 更新后packager启动失败：SyntaxError: Unexpected token ...

更新了下react native版本，突然发现packager就无法启动了。报错SyntaxError: Unexpected token ... 具体如下：

######### Starting Packager ##########

######### Executing command: react-native start --port 8081 ##########

this._nextStatusStr = util.format(format, ...args);

在这里找到了解决办法：github  原因是react native 0.46之后使用ES6语法，如果node版本太低，就无法识别...这种延伸操作符，所以需要更新到node v6以上。
