我正在尝试在我的本机应用程序上使用firebase.但它给出了一个错误.

我的App.js代码如下

import React, { Component } from 'react';
import { Text } from 'react-native';
import firebase from 'firebase';

export default class HelloWorldApp extends Component {
  componentWillMount(){
    firebase.initializeApp({
      apiKey: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
      authDomain: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
      databaseURL: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
      projectId: 'xxxxxxxxxxxxxxxxxxxx',
      storageBucket: 'xxxxxxxxxxxxxxxxxxxxxxxxxxx',
      messagingSenderId: 'xxxxxxxxxx'
    })
  }

  render() {
    return (
      <Text>Hello world!</Text>
    );
  }
}

我能做什么？谢谢
