嗨，我正在尝试使用 react-redux 设置 redux-persist，但我无法让它工作。我收到以下错误：

TypeError: _store2.default 不是函数 [了解更多] index.js:12:29

我现在如何进行设置：

store.js

import {applyMiddleware, createStore} from 'redux';
import {persistStore,persistCombineReducers} from 'redux-persist';
import storage from 'redux-persist/es/storage' // default: localStorage if web, AsyncStorage if react-native

import { logger } from 'redux-logger';
import thunk from 'redux-thunk';
import promise from 'redux-promise-middleware';
import reducer from './reducers'

const middleware = applyMiddleware(promise(), thunk, logger);

const config = {
  key: 'root',
  storage,
};

const reducers = persistCombineReducers(config, {reducer});

export const configureStore = () => {
  const store = createStore(reducers, middleware);
  const persistor = persistStore(store);
  return { persistor, store };
};

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import {BrowserRouter} from 'react-router-dom';
import {Provider} from 'react-redux';
import Bootstrap from 'bootstrap/dist/css/bootstrap.css';
import './css/app.css';
import App from './containers/App';

import { PersistGate } from 'redux-persist/es/integration/react'
import configureStore from './store';
const { persistor, store } = configureStore()


ReactDOM.render(
  <Provider store={store} >
    <PersistGate persistor={persistor}>
    <BrowserRouter>
      <App/>
    </BrowserRouter>
  </PersistGate>
  </Provider>,
  document.getElementById('root')
);

现在根据@azium 的回复，我得到：

上述错误发生在组件中： in Connect(App) (created by Route) in Route (created by withRouter(Connect(App))) in withRouter(Connect(App)) in Router (created by BrowserRouter) in BrowserRouter in PersistGate在提供者

从 App.js 调用它时：

@withRouter
@connect((store) => {
  return {
    isAuthenticated: store.auth.isAuthenticated,
  };
})

如果要使用默认导出，则需要更改：

export const configureStore = () => {
  const store = createStore(reducers, middleware);
  const persistor = persistStore(store);
  return { persistor, store };
};

至：

export default () => {
  const store = createStore(reducers, middleware);
  const persistor = persistStore(store);
  return { persistor, store };
};

或者：

const configureStore = () => {
  const store = createStore(reducers, middleware);
  const persistor = persistStore(store);
  return { persistor, store };
};

export default configureStore;

或者如果您不想使用默认导出更改：

import configureStore from './store';

至：

import { configureStore } from './store';

因此，经过一番思考和社区帮助后，我设法将问题缩小到我的 reducer 声明。我在 index.js 中使用 combineReducers 声明 reducer，而 redux-persist 说不应该。

最终 index.js 代码：

import user from './userReducer'
import auth from './authReducer'

export default ({
  user, auth
})
