rxjs v6 / redux-observable v1.0.0：运算符在史诗中不起作用

Question

我正在使用最新版本的 redux-observable 和 Rxjs，即

// My version
"redux-observable": "^1.0.0",
"rxjs": "^6.3.2"

商店 - 中间件，设置如下所示：

// Setting up middlewares
import { pingEpic } from './epics';
import pingReducer from './reducers/pingReducer';

import { combineReducers, createStore, applyMiddleware } from 'redux';
import { combineEpics, createEpicMiddleware } from 'redux-observable';

const rootReducer = combineReducers(pingReducer);
const rootEpic = combineEpics(pingEpic);

const epicMiddleware = createEpicMiddleware();

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

epicMiddleware.run(rootEpic);
export default store;

我的史诗是这样的

// pingEpic.js
import { mapTo } from 'rxjs/operator/mapTo';
import { ofType } from 'redux-observable';
export const pingEpic = action$ => action$.pipe(
    ofType('PING'),
    mapTo({ type: 'PONG' })
);

所以当我第一次执行程序时，我得到了以下错误：

我用谷歌搜索了一下，found a solution here 说要安装 rxjs-compat@6（但没有任何意义）我也安装了它！然后我运行进入以下错误：

我不知道what/where我做错了吗？任何帮助将不胜感激！

谢谢

应该是

import { mapTo } from 'rxjs/operators';

而不是

import { mapTo } from 'rxjs/operator/mapTo';
