我正在尝试使用firebaseui auth为单页Web应用程序创建登录屏幕。我复制了firebaseui的示例代码来创建登录屏幕：

<script src="/__/firebase/init.js"></script>
<script src="https://cdn.firebase.com/libs/firebaseui/3.0.0/firebaseui.js"></script>
<link type="text/css" rel="stylesheet" href="https://cdn.firebase.com/libs/firebaseui/3.0.0/firebaseui.css" />
  <script type="text/javascript">
  // FirebaseUI config.
  var uiConfig = {
    signInOptions: [
      // Leave the lines as is for the providers you want to offer your users.
      firebase.auth.GoogleAuthProvider.PROVIDER_ID,
      firebase.auth.EmailAuthProvider.PROVIDER_ID
    ]
  };

  // Initialize the FirebaseUI Widget using Firebase.
  var ui = new firebaseui.auth.AuthUI(firebase.auth());
  // The start method will wait until the DOM is loaded.
  ui.start('#firebaseui-auth-container', uiConfig);
</script>

然后我刚插入一个

<div id="firebaseui-auth-container'></div>

加载登录屏幕。常规的Firebase内容加载正常，但身份验证屏幕却无法加载。这是我得到的错误：

Uncaught Error: Could not find the FirebaseUI widget element …
