从redux persist导入persistgate将导致“超级表达式必须为null或函数,而不是未定义”

目前,我正在react redux应用程序中使用redux persist进行持久数据存储。我是根据 the documentation 是的。持久数据存储看起来不错,但是当我导入 PersistGate 从 redux-persist/integration/react ,显示 Uncaught TypeError: Super expression must either be null or a function, not undefined 是的。有人能帮我吗?

这是我的index.js:

import React from "react";
import ReactDOM from "react-dom";
import { Provider } from "react-redux";
import {createStore} from "redux";
import reducers from "./reducers";
import { persistStore, persistReducer } from 'redux-persist';
import storage from 'redux-persist/lib/storage';
import GG from './containers/gg';
import { PersistGate } from 'redux-persist/integration/react';

const persistConfig = {
  key: 'root',
  storage,
}

const persistedReducer = persistReducer(persistConfig, reducers);
let store = createStore(persistedReducer);
let persistor = persistStore(store);

ReactDOM.render(
  <Provider store={store}>
  <GG/>
  </Provider>,
  document.querySelector(".container")
);
