【问题描述】：

我已经放松了这些步骤并观看了几个有关如何将 react-native 应用程序连接到 firebase 的视频。但我仍然收到此错误：

Error: You attempted to use a firebase module that's not installed on your Android project by calling firebase.app().

Ensure you have:

1) imported the 'io.invertase.firebase.app.ReactNativeFirebaseAppPackage' module in your 'MainApplication.java' file.

2) Added the 'new ReactNativeFirebaseAppPackage()' line inside of the RN 'getPackages()' method list.

See http://invertase.link/android for full setup instructions.

   5 | 
   6 | export default function App() {
   7 | 
>  8 |   const users = firestore()
   9 |     .collection('Users')
  10 |     .get();

所以，我尝试修复错误并将其添加到我的 MainApplication

 import io.invertase.firebase.messaging.RNFirebaseMessagingPackage;
 import io.invertase.firebase.notifications.RNFirebaseNotificationsPackage;

 @Override
protected List<ReactPackage> getPackages() {
  @SuppressWarnings("UnnecessaryLocalVariable")
  List<ReactPackage> packages = new PackageList(this).getPackages();
  packages.add(new ModuleRegistryAdapter(mModuleRegistryProvider));
  packages.add(new RNFirebaseMessagingPackage());
  packages.add(new RNFirebaseNotificationsPackage());
  return packages;
}

这是我的 App.js 文件

import { StatusBar } from 'expo-status-bar';
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import firestore from '@react-native-firebase/firestore';

export default function App() {

  const users = firestore()
    .collection('Users')
    .get();

  // console.log(users);

  return (
    <View style={styles.container}>
      <Text>Open up App.js to start working on your app!</Text>
      <StatusBar style="auto" />
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});

我还添加了所有依赖项和包以及 google.json 文件，如说明。谁能帮我解决这个问题。

【解决方案1】：

我想如果你直接使用 firestore 模块，而不是 react-native-firebase/firestore 模块，这应该可以工作
