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.

解决方法:

尝试这个：

const ConnectedChat = connect(
  mapStateToProps,
  mapDispatchToProps
)(Chat);

export default ConnectedChat;

或者,您可能希望将类定义重命名为ConnectedChat并反转名称,以便可以将其导入为“聊天”.

编辑：还要确保将聊天组件导入到App文件中,如果没有,请导入addMessage操作创建者.
