1.引入

<template>
    <div class="cod-policy" ref="codPolicyBox">
      <script type="text/javascript" src="https://cdn.bootcss.com/vConsole/3.3.0/vconsole.min.js"></script>
    </div>
</template>

2.再mounted 使用

mounted () {
    setTimeout(() => {
      const a = new window.VConsole()
      console.log(a)
    }, 1000)
  }
