@Component 修饰器在此处无效。ts(1206)

此时引用组件会报错

Unknown custom element: <preview-form> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

解决办法
装饰器必须直接位于导出的类之前
示例：

@Component({
    name: "ArchiveReviewForm",
    components: {
        PreviewForm
    },
})
export class ArchiveReviewForm{}
