Store.subscribe：TypeError：__ webpack_require __ . i（...）不是函数

我想实现Redux "subscribe"方法以自动将某些状态更改保存到localstorage，正如Dan Abramov在此视频中解释的那样：Persisting the State to the Local Storage

我在视频中做了同样的事情，但是我得到了错误：

TypeError: __webpack_require__.i(...) is not a function

而且项目没有加载 . 错误指向我在store.js文件中的 store.subscribe 函数 . 你能看到这里的错误吗？有什么错误的顺序或什么？

这是store.js文件（除了其他导入）：

import {throttle} from 'lodash/throttle';

const sagaMiddleware = createSagaMiddleware();
const logger = createLogger({
    collapsed: true,
});

const middlewares = [
    sagaMiddleware,
    routerMiddleware(history),

]; 

const enhancers = [
    applyMiddleware(...middlewares)
]; 

const composeEnhancers = 
    process.env.NODE_ENV !== 'production' &&
    typeof window === 'object' &&
    window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ ?
    window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ : compose;


const persistedState = loadState();

const store = createStore(
    reducers, 
    persistedState,
    composeEnhancers(...enhancers)
);

store.subscribe(throttle(() => {
    saveState({
        cart: store.getState().cart
    });
}), 1000);

sagaMiddleware.run(rootSaga);

export default store;

如果我注释掉“store.subscribe”块，则错误消失

// store.subscribe(throttle(() => {
//  saveState({
//      cart: store.getState().cart
//  });
// }), 1000);

Store.js 导入“ index.js ”并放入提供者：

<Provider store={store}>

“ reducers ”（在createStore方法中）是一个文件，其中所有Reducer组合在一起（使用combineReducers） .

“ localStorageHanding " file I named differently than in Abramovs example , there was some conflict with files that import " localStorage”，无论如何我都没有问题......） . localStorageHandling的saveState和loadState函数与视频中的完全相同：

export const loadState = () => {

    try{

        const serializedState = localStorage.getItem('state');
        if(serializedState === null){
            return undefined;
        }

        return JSON.parse(serializedState);
    }catch(err){
        return undefined;
    }

}


    export const saveState = (state) => {

        try{
            const serializedState = JSON.stringify(state);
            localStorage.setItem('state', serializedState);

        }catch(err){

        }
    }
