问题：
did you register the component correctly? For recursive components, make sure to provid the "name" option
在做项目的时候，引入其他组件时出现以下问题

原因：
如下是原来的错误代码，因为将components写错成了component

import ComponentA from './ComponentA.vue'
import ComponentB from './ComponentB.vue'
export default {
  component: {
    ComponentA,ComponentB
  },
  // ...
}

解决方法：
将component更正为components

import ComponentA from './ComponentA.vue'
import ComponentB from './ComponentB.vue'
export default {
  components: {
    ComponentA,ComponentB
  },
  // ...
}
