报错：props default 数组／对象的默认值应当由一个工厂函数返回
在定义Prop的时候，默认default的值如果是数组或者对象的话，应当由一个工厂函数返回
//返回数组 @Prop({ type: Array, default: ()=>[] }) rules?: Array<object>; //返回对象 @Prop({ type: Object, default: ()=>{} }) rules?:object;
报错：Props with type Object/Array must use a factory function to return the default value
