Reactjs epicMiddleware.run（rootEpic）from'；可观察的重复次数'；

无法解决此问题，系统希望从“redux observable”导入{epicMiddleware.run（rootEpic）}行中的“，”而不是“.” 然而，我是根据官方文件写的

这是我的代码：

import React from 'react'
import ReactDOM from 'react-dom'
import './index.css'
import App from './App'

import { createStore, applyMiddleware } from 'redux';
import { epicMiddleware.run(rootEpic) } from 'redux-observable';
import { Provider } from 'react-redux';
import rootReducer from './reducers/root';
import { rootEpic } from './epics';


const epicMiddleware = epicMiddleware.run(rootEpic);

const store = createStore(rootReducer, applyMiddleware(epicMiddleware));

const appWithProvider = (
    <Provider store={store}>
        <App />
    </Provider>
);


ReactDOM.render(appWithProvider, document.getElementById('root'))

您的导入声明是错误的，您应该按照下面的方式导入

import { createEpicMiddleware } from 'redux-observable';
import { rootEpic } from './epics';

像这样使用它

const epicMiddleware = createEpicMiddleware();
epicMiddleware.run(rootEpic);

const epicMiddleware = createEpicMiddleware();
epicMiddleware.run(rootEpic);
