[Vue warn]: Property or method "message" is not defined on the instance but referenced during render

《错误》[Vue warn]: Property or method “message” is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

当出现这个错误的时候：
我认真的检查了发现是我的 DATA 打成了 DATE

还有在div绑定id的时候忘记加上引号了。
