如何使用字体图标更改select标记内的箭头图标。我正在使用Vue-Cli。我已经在main.js中导入了fontawesome

npm install @fortawesome/fontawesome-svg-core
npm install @fortawesome/free-solid-svg-icons
npm install @fortawesome/vue-fontawesome

import { library } from '@fortawesome/fontawesome-svg-core'
import { faChevronDown } from '@fortawesome/free-solid-svg-icons'
import { FontAwesomeIcon } from '@fortawesome/vue-fontawesome'

library.add(faChevronDown)
Vue.component('font-awesome-icon', FontAwesomeIcon)

<template>
  <div>
    <select>
      <option value="option1">Option 1</option>
      <option value="option2">Option 2</option>
      <option value="option3">Option 3</option>
    </select>
    <font-awesome-icon icon="chevron-down" />
  </div>
</template>
