尝试从react-redux使用connect()函数时,我收到以下错误：

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object.

Check the render method of `App`.

这是应用程序：

import { Provider } from 'react-redux';
import configureStore from './store';
const App = class extends React.PureComponent {
  render() {
    const { title } = this.context;
    return (
      <div className="center-screen">
        {title}
        <Provider store={configureStore()}>
          <Chat />
        </Provider>
      </div>
    );
  }
};

这是聊天的相关代码结尾：

import { connect } from 'react-redux';


  ...


    const mapStateToProps = state => ({
  ...state
});
const mapDispatchToProps = dispatch => ({
  addMessage: () => dispatch(addMessage)
});

export default connect(
  mapStateToProps,mapDispatchToProps
)(Chat);

使用：“ export default Chat”代替connect时,它工作正常.
