Vue received a Component which was made a reactive object.

[Vue warn]: 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.

try this solution: https://jskoa.com/?p=8666
use the Item component in setup() instead of in data(). It works for me.
Be Like this:

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

data(){
return{
Search
}
},`

=>

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

setup(props, context){

return {
Search //这return同样在模板中能显示
}

},
`

Hello my friends !!

I will show you how to do with Options API 👍

<script> import { Search } from "@element-plus/icons-vue"; import { shallowRef } from "vue"; components: { Search }, Data( ) { return { Search : shallowRef( Search ) } } </script>

-You have to import Search icon from '@element-plus/icons-vue'
-You have to import shallowRef from 'vue'
-You have to add your icon name Search in the components
-You have to add your icon name Search in the Data as you see and the error massage will not show again 👍

If this helped you please give me 👍 for everyone see the solution.
Byee !
