我在我的项目中使用“react-redux-firebase”，并希望将 firebase 集成到 react-thunk 中。在本地一切正常，但在将项目部署到 Firebase 托管时出现错误。

未捕获的错误：Firebase 实例尚不存在。检查您的撰写功能。

这里有什么问题？

store.js

import { createStore, compose, applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import { reduxFirestore, getFirestore } from 'redux-firestore';
import { reactReduxFirebase, getFirebase } from 'react-redux-firebase';

import rootReducer from './reducers/index';
import fbConfig from '../fbConfig';

/* eslint-disable no-underscore-dangle */
const composeEnhancers =
  process.env.NODE_ENV !== 'production' &&
  typeof window === 'object' &&
  window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__
    ? window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__({})
    : compose();
/* eslint-enable */

const enhancer = composeEnhancers(
  applyMiddleware(
    thunk.withExtraArgument({
      getFirebase,
      getFirestore
    })
  ),
  reduxFirestore(fbConfig),
  reactReduxFirebase(fbConfig, {
    useFirestoreForProfile: true,
    userProfile: 'users'
  })
);

const configureStore = preloadedState =>
  createStore(rootReducer, preloadedState, enhancer);

const store = configureStore({});

export default store;

fbConfig.js

import firebase from 'firebase/app';
import 'firebase/firestore';
import 'firebase/auth';

const firebaseConfig = {
  apiKey: ...,
  authDomain: ...,
  databaseURL: ...,
  projectId: ...,
  storageBucket: ...,
  messagingSenderId: ...,
  appId: ...
};

firebase.initializeApp(firebaseConfig);
firebase.firestore().settings({});

export default firebase;

减速器/索引

import { combineReducers } from 'redux';
import { firestoreReducer } from 'redux-firestore';
import { firebaseReducer } from 'react-redux-firebase';

import auth from './auth';

const rootReducers = combineReducers({
  auth,
  firestore: firestoreReducer,
  firebase: firebaseReducer
});

export default rootReducers;

这是因为你没有通过 reduxFirestore(fbConfig) 来撰写

这可能会对您有所帮助，请查看此 github 链接 https://github.com/prescottprue/react-redux-firebase/issues/620#issuecomment-458344113
