javascript - 预期 reducer 是一个函数 - React Native、Redux

Question

我正在学习 React Native 和 Redux，但我的代码中遇到了一个我无法解决的问题。当我在 iPhone 模拟器 (iOS 10.3) 上运行我的代码时，出现错误:“Expected the reducer to be a function”。

这是我的所有代码(很短，很基础):

src/app.js:

import React from 'react';
import { View } from 'react-native';
import { Provider } from 'react-redux';
import { createStore } from 'redux';
import reducers from './reducers';
import {Header} from 'native-base';

const App = () => {
  return(
    <Provider store={createStore(reducers)}>
      <View>
        <Header />
      </View>
    </Provider>
  )
}

export default App;

src/reducers/index.js:

import { combineReducers } from 'redux';

export default combineReducers({
    libraries: () => []
});

index.ios.js:

import {AppRegistry} from 'react-native';
import App from './src/app';

AppRegistry.registerComponent('project', () =>  App);

the exact error message

谢谢大家 荣荣。

我犯的一个错误是使用 import {reducers } from '../reducers/myReducer'; 而不是 import reducers from '../reducers/myReducer';, which yielded the same error message.
