打开项目不同的页面都出现vue的警告

[Vue warn]: Property or method "toJSON" 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.

最后发现是vConsole导致的问题，关闭就可以了
