用户已登录,但重定向不起作用。如何解决这些问题?以下是

登录组件代码:

const Login = ({ props }) => {
    const [email, setEmail] = useState();
    const [password, setPassword] = useState();

    const alert = useAlert();
    const dispatch = useDispatch();

    const { isAuthenticated, error, loading } = useSelector(
      (state) => state.auth
    );

    useEffect(() => {
      if (isAuthenticated) {
        props.history.push("/");
      }

      if (error) {
        alert.error(error);
        dispatch(clearErrors());
      }
    }, [dispatch, alert, error, loading, props, isAuthenticated]);

    const submitHandler = (e) => {
      e.preventDefault();
      dispatch(login(email, password));
    };  
    return ()
}

错误:

TypeError: Cannot read property 'history' of undefined

你从 props 中解构了 props 吗?也许你的意思是 ({ history, aProp, bProp })
