ruby-on-rails - 如何修复“未捕获的 TypeError：调度不是函数”？

Question

我在尝试在窗口上执行调度操作时遇到此错误：“未捕获的 TypeError：调度不是函数”。

我仔细检查了语法。

Uncaught TypeError: dispatch is not a function

export const fetchAllSpots = () => dispatch => (
    APIUtil.fetchAllSpots().then(spots => 
    dispatch(receiveAllSpots(spots)))
);

const receiveAllSpots = payload => ({
    type: RECEIVE_ALL_SPOTS,
    payload
});

window.fetchAllSpots = fetchAllSpots();

你添加dispatch到路由器连接？就像是 ：

export default connect(mapStateToProps, dispatch => ({
  dispatch, ComponentNameHere})) (ComponentNameHere)
