Redux-Persist： 类型错误： 无法读取未定义的属性'getItem'

Question

我正在开发一个react应用程序，最近在我的mac上升级到node12.10.0，遇到了很多包问题。我在我的项目中升级了很多包，但当我调用persistor.purge((：时，似乎出现了一个错误

TypeError: Cannot read property 'getItem' of undefined
getStoredState
node_modules/redux-persist/es/getStoredState.js:19
16 |   deserialize = defaultDeserialize;
17 | }
18 | 
> 19 | return storage.getItem(storageKey).then(function (serialized) {
20 |   if (!serialized) return undefined;else {
21 |     try {
22 |       var state = {};

> 26 | getStoredState({}).then((err, restoredState) => {
27 |     if(restoredState) {
28 |         let storedAppVersion = restoredState.app ? restoredState.app.version : null;
29 |         // Purge the persisted state if the version has changed

当我在以下reducer代码中点击persistor.purge((时，错误本身似乎发生了：

case REHYDRATE:
let isValid = isTokenInLocalStorageValid();
if(isValid) {
let storedState = action.payload.user;
let newState = Object.assign({}, storedState, { status: null });
return newState;
}
debugger;
debugger;
persistor.purge();

这是我创建潜望镜和商店的代码：

export const history = createBrowserHistory();
const sagaMiddleware = createSagaMiddleware();
const initialState = {}
const middleware = [
thunk,
sagaMiddleware,
routerMiddleware(history)
]
const composedEnhancers = compose(
applyMiddleware(...middleware)
)
debugger;
debugger;
const persistConfig = {
key: 'root',
storage: localforage,
}
const persistedReducer = persistReducer(persistConfig, rootReducer(history));
const store = createStore(
persistedReducer,
initialState,
composedEnhancers
)
store.runSaga = sagaMiddleware.run(sagas);
let persistor = persistStore(store)
export default () => {
return { store, persistor }
}

我查看了设置示例，没有看到问题可能在哪里。

出于某种原因，它说存储是未定义的。我相信你很可能已经检查过了，但在错误指向的文件中；您正在导入存储吗？
