组件没有预期的属性，而React和Redux开发工具具有预期的状态和属性

npm install react-redux

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

ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root')
);

import React from 'react';
import { connect } from 'react-redux';

const MyComponent = (props) => {
  // 使用从 Redux store 映射的 props
  const { myProp } = props;

  return (
    <div>
      {/* 渲染 myProp */}
    </div>
  );
};

// 将 Redux store 中的 state 映射到组件的 props
const mapStateToProps = (state) => ({
  myProp: state.myProp,
});

// 将 Redux store 中的 dispatch 映射到组件的 props
const mapDispatchToProps = (dispatch) => ({
  // 如果需要，可以在这里添加 dispatch 函数
});

// 使用 connect 函数连接组件和 Redux store
export default connect(mapStateToProps, mapDispatchToProps)(MyComponent);

import { createStore, combineReducers } from 'redux';

const initialState = {
  myProp: 'initial value',
};

const myReducer = (state = initialState, action) => {
  switch (action.type) {
    case 'UPDATE_MY_PROP':
      return { ...state, myProp: action.payload };
    default:
      return state;
  }
};

const rootReducer = combineReducers({
  myProp: myReducer,
});

const store = createStore(rootReducer);

export default store;
