在学习教程时，我得到了这个 store.dispatch 不是函数错误。我已经搜索了一段时间的 stackoverflow，但似乎找不到任何错误。我错过了什么？

import {configureStore, combineReducers} from '@reduxjs/toolkit'
import cartReducer from './cartRedux'
import userReducer from './userRedux'
import {
  persistStore,
  persistReducer,
  FLUSH,
  REHYDRATE,
  PAUSE,
  PERSIST,
  PURGE,
  REGISTER,
} from 'redux-persist'
import storage from 'redux-persist/lib/storage'

const persistConfig = {
  key: 'root',
  version: 1,
  storage,
}

const rootReducer = combineReducers({user: userReducer, cart: cartReducer})
const persistedReducer = persistReducer(persistConfig, rootReducer)

export const store = () => configureStore({
  reducer: persistedReducer,
  middleware: (getDefaultMiddleware) =>
    getDefaultMiddleware({
      serializableCheck: {
        ignoredActions: [FLUSH, REHYDRATE, PAUSE, PERSIST, PURGE, REGISTER],
      },
    }),
})


export const persistor = persistStore(store)

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import {Provider} from 'react-redux'
import {store, persistor} from './redux/store'
import { PersistGate } from 'redux-persist/integration/react'

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

【解决方案1】：

您似乎已将 store 声明为返回已配置存储的函数。

export const store = () => configureStore({ // <-- a function
  reducer: persistedReducer,
  middleware: (getDefaultMiddleware) =>
    getDefaultMiddleware({
      serializableCheck: {
        ignoredActions: [FLUSH, REHYDRATE, PAUSE, PERSIST, PURGE, REGISTER],
      },
    }),
})

然后你传递了对这个store函数persistStore的引用

export const persistor = persistStore(store) // <-- store not invoked

虽然您可以在每个地方都调用store 函数，但这会很糟糕，因为您会在应用程序的不同部分有效地创建多个无法协同工作的商店实例。您应该只导出并使用已配置的存储对象。

export const store = configureStore({
  reducer: persistedReducer,
  middleware: (getDefaultMiddleware) =>
    getDefaultMiddleware({
      serializableCheck: {
        ignoredActions: [FLUSH, REHYDRATE, PAUSE, PERSIST, PURGE, REGISTER],
      },
    }),
});

export const persistor = persistStore(store);

非常感谢 BUD.. 它对我有用，解释也很好。
