typescript无法调用类型缺少调用签名的表达式？

Question

我在combineReducers中拨打import { combineReducers } from 'redux-immutable'（typescript），如下所示：

return combineReducers({
    byId,
    visibleIds
})(state, action)

但是打字稿抱怨这个：

Cannot invoke an expression whose type lacks a call signature.

所以我看到了类型定义文件：

declare module "redux-immutable" {
    export function combineReducers(reducers : Object): Object;
}

如何正确调用combineReducer？

Answer 1

类型定义错误，这应该有效：

declare module "redux-immutable" {
    export function combineReducers(reducers : Object): Function;
}

虽然类型定义是官方Redux typings是：

function combineReducers<S>(reducers: ReducersMapObject): Reducer<S>;
