似乎老师的代码编错了， 代码可能是

<button class="flex ml-auto gap-2">
  <svg stroke="currentColor" fill="none" stroke-width="2" viewBox="0 0 24 24" stroke-linecap="round" stroke-linejoin="round" class="h-4 w-4" height="1em" width="1em" xmlns="http://www.w3.org/2000/svg">
    <path d="M16 4h2a2 2 0 0 1 2 2v14a2 2 0 0 1-2 2H6a2 2 0 0 1-2-2V6a2 2 0 0 1 2-2h2"></path>
    <rect x="8" y="2" width="8" height="4" rx="1" ry="1"></rect>
  </svg>
  Copy code
</button>

而且没有评测数据
