javascript - 缺少默认作用域插槽 Vuetify

Question

我正在查看 vues 页面上的教程以添加工具提示。 https://vuetifyjs.com/en/components/tooltips

对于单个按钮来说似乎工作得很好。

但是，它在 v-item 中不起作用。我收到一条控制台消息，内容为

'[Vuetify] v-item is missing a default scopedSlot'

<v-item v-for="foo in bars" :key=`${foo}`>
  <v-tooltip>
    <v-btn slot="activator">
      <v-icon>some-icon</v-icon>
    </v-btn>
    <span>Some tooltip text</span>
  </v-tooltip>
</v-item>

我尝试在上面的代码中添加一些内容，例如将 slot="activator"添加到 v-item 并将 slot-scope="activator"添加到 v-btn，但似乎没有任何效果完全正确。关于我做错了什么有什么建议吗？

new Vue({
  el: '#app',
  data() {
    return {
      bars: ['a', 'b', 'c']
    }
  }

调试代码片段后，我通过添加 slot-scope="i" 找到了解决方案到tooltip组件如 <v-tooltip slot-scope="i" right> :

new Vue({
  el: '#app',
  data() {
    return {
      bars: ['home', 'event', 'info']
    }
  }

})
