NativeScript:获取模板解析错误:只有 void 和 foreign 元素可以自关闭

NativeScript : Getting Template parse errors: Only void and foreign elements can be self closed

我正在使用 NativeScript 创建示例应用程序。 运行 我的 android 设备中的应用程序出现模板解析错误。

我在模板中的代码是:

<Page xmlns="http://schemas.nativescript.org/tns.xsd">
  <Page.actionBar>
      <ActionBar title="My ActionBar"/>
  </Page.actionBar>
</Page>

我收到以下错误:

Template parse errors:
Only void and foreign elements can be self closed "ActionBar" ("<Page xmlns="http://schemas.nativescript.org/tns.xsd">
  <Page.actionBar>
      [ERROR ->]<ActionBar title="My ActionBar"/>
  </Page.actionBar>
</Page>"): AppComponent@2:6

Error: Template parse errors:

  <Page.actionBar>
      [ERROR ->]<ActionBar title="My ActionBar"/>

</Page>"): AppComponent@2:6

当我添加结束标签时,显示另一个错误:

<ActionBar title="My ActionBar"></ActionBar> - 你不能使用自闭标签。
