未捕获的错误：createSagaMiddlewareHelpers期望sagaMiddleware包含run方法

Question

我尝试使用redux-saga-watch-actions库，但是现在我在整个Internet上遇到了一些无法解决的错误。我之所以无法想象，是因为我按照这个有用软件包的原始手册中所述进行了所有操作。

我的sagaHelper文件

import createSagaMiddleware from 'redux-saga'
import createSagaMiddlewareHelpers from 'redux-saga-watch-actions/lib/middleware'
import watchSearch from '../routes/watchSearch/modules/saga'
import watchHub from '../modules/saga'

const sagaMiddleware = createSagaMiddleware()
const runSaga = saga => sagaMiddleware.run(saga)

const { injectSaga, cancelTask } = createSagaMiddlewareHelpers(runSaga) // that is where I got an error

export const rootSaga = function * () {
  yield all([
    watchHub(),
    watchSearch()
  ])
}

export { cancelTask, injectSaga, runSaga }
export default sagaMiddleware

我的createStore文件：

import saga, { rootSaga, runSaga } from '../saga/sagaHelper'

export default (initialState = {}) => {

  const store = createStore(
    makeRootReducer(),
    initialState,
    compose(responsiveStoreEnhancer, applyMiddleware(saga))
  )

  store.runSaga = runSaga
  runSaga(rootSaga)

  return store
}
