没有简化器为“管理”规定。 React Admin错误

Question

我在反应添加面板中使用redux。我正在关注文档，包括另一个Redux中的React-Admin应用程序

但是我会遇到此错误。

没有为密钥“ admin”提供减少

我认为 admindreducer 无法从“ react-admin”中导入。我在升级我的错误后面临此错误React Admin从3.18到4.0.0。它与版本不匹配有关吗？

在这里，我的 createadminstore.js

import { applyMiddleware, combineReducers, compose, createStore } from "redux";
import { routerMiddleware, connectRouter } from "connected-react-router";
import createSagaMiddleware from "redux-saga";
import { all, fork } from "redux-saga/effects";
import { adminSaga, adminReducer, USER_LOGOUT } from "react-admin";

export default ({ authProvider, dataProvider, history }) => {
  const reducer = combineReducers({
    admin: adminReducer,
    router: connectRouter(history),
    // add your own reducers here
  });
  const resettableAppReducer = (state, action) =>
    reducer(action.type !== USER_LOGOUT ? state : undefined, action);

  const saga = function* rootSaga() {
    yield all(
      [
        adminSaga(dataProvider, authProvider),
        // add your own sagas here
      ].map(fork)
    );
  };
  const sagaMiddleware = createSagaMiddleware();

  const composeEnhancers =
    (process.env.NODE_ENV === "development" &&
      typeof window !== "undefined" &&
      window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ &&
      window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__({
        trace: true,
        traceLimit: 25,
      })) ||
    compose;

  const store = createStore(
    resettableAppReducer,
    {
      /* set your initial state here */
    },
    composeEnhancers(
      applyMiddleware(
        sagaMiddleware,
        routerMiddleware(history)
        // add your own middlewares here
      )
      // add your own enhancers here
    )
  );
  sagaMiddleware.run(saga);
  return store;
};
