Why my vue3 could not work with vue-class-component

<script>
 import * as Vue from 'vue'
import Component from 'vue-class-component'

@Component
export default class HelloWorld extends Vue {
  //my operation
}

</script>

It's a simple example for vue-class-component. However, when I run my project, the browser shows the following error:

Uncaught TypeError: Class extends value #<Object> is not a constructor or null
at eval (HelloWorld.vue?e90b:39:1)

Why does this happen? and the cmd also shows such a warning:

in ./node_modules/vue-class-component/dist/vue-class-component.esm.js

I'm confused that is any problem with my version about vue-class-component ? What should I do… ?

Component doesn't support in Vue3. So instead of Component you can use Options and if there is any Component you can define them in Options. I also faced same issue so I tried importing Vue from vue-class-component because here Vue is declared as Vue Constructor and export that.

<script>

import {Vue,Options} from 'vue-class-component'
@Options({
    components: {}
})
export default class HelloWorld extends Vue {
  //my operation
}

</script>
