The data property "num" is already declared as a prop. Use prop default value instead.

在写父组件子组件相互传递数据的时候，出现The data property "num" is already declared as a prop. Use prop default value instead.

这里意思是这个data的属性num已经在prop声明了，使用prop默认的值替代。因为num我在父组件已经创建声明后面又在子组件的data

声明和初始化，冲突。

所以报这个错，然后需要把儿子的那个data函数里的num删除，便可以解决报错。

本人是vue的新手，比较菜，有错的望前辈们指出。。
