按照文档上的方式引入组件，但是还是会报错说没有注册
引入方式如下：
import { Cell, CellGroup, Field, Dialog } from ‘vant‘;
components: {
[CellGroup.name]: CellGroup,
[Field.name]: Field,
[Cell.name]: Cell,
[Dialog.name]: Dialog,
NavBar
},
<van-dialog> - did you register the component correctly? For recursive components, make sure to provide the "name" option
如上面展示的一样的报错，解决方式是
[Dialog.Component.name]: Dialog.Component,
加上Component
