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)))

【参考方案1】：

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