Question

store.js

import {createStore, applyMiddleware} from 'redux';
import createLogger from 'redux-logger';
import rootReducer from './reducers/index';

const logger = createLogger();

const createStoreWithMiddleware = applyMiddleware(logger)(createStore);

export default function configureStore(initialState) {
  return createStoreWithMiddleware(rootReducer, initialState);
}

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import TrackList from './components/TrackList';
import {configureStore} from './store';
import * as actions from './actions';

const tracks = [
  {
    id: 1,
    title: 'Title 1'
  },
  {
    id: 2,
    title: 'Title 2'
  }
];

const store = configureStore();
store.dispatch(actions.setTracks(tracks));

ReactDOM.render(
  <TrackList />,
  document.getElementById('app')
);

文件夹src包含index.js和store.js

显示消息Uncaught TypeError：（0，_ store.configureStore）不是F12时的函数

帮助我谢谢

这个答案可能不再适用。请参阅以下评论中的讨论，了解为什么以及实际解决方案应该是什么。

您从模块中导出单个函数，因此导入应为：

import configureStore from './store';

你会用

import {configureStore} from './store';

如果您的导出看起来像

export default {
  configureStore: function(initialState) {
    return createStoreWithMiddleware(rootReducer, initialState);
  }
}

未捕获的TypeError：（0，_ store.configureStore）不是函数
