TypeError:中间件不是的函数错误-- v3迁移指南

Question

我正在使用这些包，但当我使用react创建一个新的create-react-app应用程序时，突然在中间件组合上出现了这个错误。我有以下包裹。你能解释一下我在这里缺少什么吗？HELP

也仰慕这份指南

不能将中间件数组作为参数传递给applyMiddleware。应该将每个中间件作为单独的参数传递，尝试如下：

export default () => {
    return createStore(
        rootReducer,
        initialState,
        applyMiddleware(thunk.withExtraArgument(getFirebase))
    )
}
