Question

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
    at Proxy.created (vue-select.js?4a7a:1)
    at callWithErrorHandling (runtime-core.esm-bundler.js?5c40:155)

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>
