TypeScript中的Firestore减速器

Question

我为我的减速器编写了以下代码：

import { Reducer, combineReducers } from 'redux';
import { routerReducer } from 'react-router-redux';
import { firebaseReducer } from 'react-redux-firebase';
import { firestoreReducer } from 'redux-firestore';

const reducers: Reducer<ApplicationState> = combineReducers<ApplicationState>({
  firebase: firebaseReducer,
  firestore: firestoreReducer,
  router: routerReducer
});

export { reducers };

我几乎跟随了这里的教程

但是，firestore还原程序发出以下消息：

Argument of type '{ firebase: typeof firebaseReducer; firestore: typeof firestoreReducer; router: Reducer<RouterSta...' is not assignable to parameter of type 'ReducersMapObject'.
  Property 'firestore' is incompatible with index signature.
    Type 'typeof firestoreReducer' is not assignable to type 'Reducer<any>'.
      Type 'typeof firestoreReducer' provides no match for the signature '(state: any, action: AnyAction): any'.

问题可能是什么，如何解决？

Answer 1

似乎TS正在寻找一个Reducer在firebaseReducer的位置，但发现了其他的东西。为了看“其他东西”是什么，我去看了类型，找到这个，和.立刻感到困惑。看起来这些类型不仅仅是破碎的，它们甚至可能不存在。手工铸造可能是你最好的选择。

const reducers: Reducer<ApplicationState> = combineReducers<ApplicationState>({
  firebase: firebaseReducer,
  firestore: firestoreReducer as Reducer<ApplicationState>,
  router: routerReducer
});

我也会考虑打开一个问题或公关的这一点。，这有点令人费解，以前没人遇到过这种情况。
