Inoic：离子头像未显示

Question

item-avatar 在我的项目中不起作用，它根本不显示 item-avatar 元素。

  <ion-content padding>
  <ion-list>
      <ion-list-header>
          Recent Conversations
      </ion-list-header>
      <ion-item>
          <item-avatar start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </item-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>

      <ion-item item-start>
          <item-avatar start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </item-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>

      <ion-item slot="start">
          <item-avatar start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </item-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>
  </ion-list>
</ion-content>

你犯了一个错误<item-avatar start>

改成 ：

<ion-avatar item-start>
    <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
 </ion-avatar>

工作代码：

<ion-content padding>
  <ion-list>
      <ion-list-header>
          Recent Conversations
      </ion-list-header>
      <ion-item>
          <ion-avatar item-start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </ion-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>

      <ion-item item-start>
          <ion-avatar item-start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </ion-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>

      <ion-item slot="start">
         <ion-avatar item-start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </ion-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>
  </ion-list>
</ion-content>
