我正在尝试运行 react redux，但不幸的是我得到了未定义的错误。以下是错误显示：

  Uncaught TypeError: Cannot read properties of undefined (reading 'getState')

错误似乎来自 index.js 文件，特别是 Provider store={store}，但我可能是错的。

这是我使用的文件列表：

index.js

import App from './App';
import React from 'react';
import ReactDOM from 'react-dom/client';
import { Provider } from 'react-redux';
import store from './store';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <Provider store={store}>  {/*  This will make store accessible to the entire component tree  */}
      <App />
    </Provider>
  </React.StrictMode>
);

store.js

import { configureStore } from "@reduxjs/toolkit";
import pizzaReducer from './pizzaSlice';

const store = configureStore({
reducer: {
pizza: pizzaReducer,
}
})

export default store.reducer;

pizzaSlice.js

import { configureStore } from "@reduxjs/toolkit";
import pizzaReducer from './pizzaSlice';

const store = configureStore({
reducer: {
pizza: pizzaReducer,
}
})
export default store.reducer;

App.js

import { useDispatch, useSelector } from 'react-redux';
import { addTopping, toggleGluten } from './pizzaSlice';
import './App.css';

function App() {

  const pizza = useSelector(state => state.pizza);    
  const dispatch = useDispatch();  // dispatch action

  return (
    <div className="App">
        <h1>Pizza</h1>
          {
           pizza.toppings.map(toppings => (
             <div key={toppings}>{toppings}</div> 
           ))
         }
         <button onClick={dispatch(addTopping('ham'))}> Add Ham </button>
         <button onClick={dispatch(addTopping('mushroom'))}> Add Mushroom </button>
         <button onClick={dispatch(addTopping('pepperoni'))}> Add Pepperoni </button>
         <button onClick={dispatch(toggleGluten())}> Toogle Gluten </button>
    </div>
  );
}

export default App;

我尝试过使用 redux 中的 createStore，但它也不起作用
