我安装了一个带有 vue-cli 和 typescript 的全新 Vue 3。 一切运行 但是当我添加一个 https://vue-select.org/ 包时 我在浏览器控制台上收到此错误

Uncaught (in promise) TypeError: this.$on is not a function

简单例子

Home.vue
<template>
  <div class="home">
    <img alt="Vue logo" src="../assets/logo.png">
    <vSelect :options="[{label: 'Canada',code: 'ca'}]"></vSelect>
  </div>
</template>

<script lang="ts">
import { Options,Vue } from 'vue-class-component';
import HelloWorld from '@/components/HelloWorld.vue'; // @ is an alias to /src
import vSelect from 'vue-select';

@Options({
  components: {
    HelloWorld,vSelect
  },})
export default class Home extends Vue {}
</script>
