解决：Vue received a Component which was made a reactive object. This can lead to unnecessary performance overhead, and should be avoided by marking the component with `markRaw` or using `shallowRef` instead of `ref`

解决：这问题在vue3才会出现

不能把变量写在data里面，要写在setup函数中，并return

import {
  Search
} from '@element-plus/icons'


data(){
  return{
     Search
  }
},

改成

import {
Search
} from '@element-plus/icons'

setup(props, context){
  
  return {
    Search  //这return同样在模板中能显示
  }

},
