这个错误有没有解决方法:在"Connect(App)“的上下文中找不到"store”。要么将根组件包装在<Provider>中

import { Provider } from 'react-redux';
import store from './store';

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

import { connect } from 'react-redux';

class App extends React.Component {
  // ...
}

export default connect()(App);

npm install redux react-redux

import { Provider } from 'react-redux';
import { createStore } from 'redux';
import rootReducer from './reducers';

const store = createStore(rootReducer);

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