报错：

[Vue warn]: Unknown custom element: <d01-person-thing> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

解决：

组件循环引用（两个组件同时引用另一个组件时）发生这个错误，在components中通过以下方式引用可以解决

components: {D01PersonThing : ()=>import(""@/components/D01PersonThing"),},
