如何使用persistStore()持久化存储？我遇到一个错误：“store没有有效的缩减程序”。

import { createStore } from 'redux';
import { persistStore, persistReducer } from 'redux-persist';
import storage from 'redux-persist/lib/storage'; // 指定存储方式，默认为localStorage

// 创建reducer
const rootReducer = combineReducers({
  // 你的reducer
});

// 持久化配置
const persistConfig = {
  key: 'root', // 存储的key，可以自定义
  storage, // 指定存储方式，默认为localStorage
};

const persistedReducer = persistReducer(persistConfig, rootReducer);

const store = createStore(persistedReducer);
const persistor = persistStore(store);

export { store, persistor };

import { PersistGate } from 'redux-persist/integration/react';
import { store, persistor } from './store';

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