React native expo，您试图通过调用 firebase.app() 来使用未安装在您的 Android 项目上的 firebase 模块

Question

在我的项目中，我使用 React 本机 firebase 来获取 Analytics，而我的项目是 expo 裸流程，我只是遵循了这个 https://rnfirebase.io/ 文档，但是在运行应用程序时遇到了类似的错误

backend.js:2173 Possible Unhandled Promise Rejection (id: 3):
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.

我的 Android MainApplication.java

import io.invertase.firebase.app.ReactNativeFirebaseAppPackage; <---added for firebase   
private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
@Override
public boolean getUseDeveloperSupport() {
  return BuildConfignfig.DEBUG;
}

@Override
protected List<ReactPackage> getPackages() {
  List<ReactPackage> packages = new PackageList(this).getPackages();
  packages.add(new ModuleRegistryAdapter(mModuleRegistryProvider));
  packages.add(new ReactNativeFirebaseAppPackage());<---- added for firebase
  return packages;
}

我也试过用config-pluginhttps://docs.expo.dev/guides/config-plugins/也没有用，错误没有解决。

我有一个 expo 应用程序并使用了此链接...

如果您退出 expo 或从 bareworkflow 开始，可能会有所不同

https://docs.expo.dev/guides/using-firebase/#using-expo-with-firestore

有一个 firebase.js 文件并导入您需要的不同模块

以我们的为例

import { initializeApp } from "firebase/app"
import { getFirestore } from 'firebase/firestore';
import Constants from "expo-constants"
import "firebase/auth"

 // TODO: Add SDKs for Firebase products that you want to use
// https://firebase.google.com/docs/web/setup#available-libraries

// Your web app's Firebase configuration -- from firebase console
// For Firebase JS SDK v7.20.0 and later, measurementId is optional

const firebaseConfig = {
  apiKey: xxxxxxx,
  authDomain: xxxxxxx,
  databaseURL: xxxxxxxxx,
  projectId: xxxxxxxxx,
  storageBucket: xxxxxxxxx,
  messagingSenderId: xxxxxxxxx,
  appId: xxxxxxxxx,
  measurementId: xxxxxxxxx,
 }

// Initialize Firebase
const Firebase = initializeApp(firebaseConfig)
const firestore = getFirestore(); <--- our added firestore module
export default [Firebase, firestore]

确保根据 FB 包安装指南添加了 @firebase/module-name
