firebase-authentication - 当前环境不支持指定的持久化类型

Question

https://firebase.google.com/docs/auth/web/auth-state-persistence

The default for web browser and React Native apps is local (provided the browser supports this storage mechanism, eg. 3rd party cookies/data are enabled) whereas it is none for Node.js backend apps.

当我在我的 React Native Android 应用程序中尝试以下操作时:

const signIn = () =>
  firebase.auth().setPersistence(firebase.auth.Auth.Persistence.LOCAL).then(() => {
    return firebase.auth().signInAnonymously();
  });

我收到以下错误:

The current environment does not support the specified persistence type.

这是一个错误还是我遗漏了文档中的某些内容？

环境:

"dependencies": {
    "firebase": "^4.5.0",
    "react": "16.0.0-alpha.12",
    "react-native": "^0.48.4",
  }

Android 7.0

似乎在选择性导入 firebase 模块时存在错误。
更改导入自

import * as firebase from 'firebase/app';
import 'firebase/auth';

到

import firebase from 'firebase';  

解决了这个问题。
