store.js

import { createStore, combineReducers, applyMiddleware } from 'redux'
import { composeWithDevtools } from 'redux-devtools-extension'
import thunk from 'redux-thunk'
import { postReducer, 
    specialityReducer, 
    courseReducer, 
    teacherReducer, 
    lessonReducer 
} from './reducers'



export default createStore(combineReducers({postReducer, specialityReducer, courseReducer, teacherReducer, lessonReducer}),composeWithDevtools(applyMiddleware(thunk)))

尝试将对象传递给 combineReducers 并在所有 reducer 之前给出名称。 combineReducers({ reducerName: reducerFunction });
