React relay injectNetworkLayer不是函數

Question

我正在按照來自lynda的教程：「構建和部署完整堆棧響應應用程序」中的「注入中繼網絡層」一章。有在index.js，試圖建立一個網絡層，程序編譯成功，但我收到在瀏覽器中出現以下錯誤：

類型錯誤：__WEBPACK_IMPORTED_MODULE_4_react_relay ___ default.a.injectNetworkLayer不是一個函數

index.js文件是：

import React from 'react' 
import ReactDOM from 'react-dom' 
import {Router, browserHistory, applyRouterMiddleware} from 'react-router' 
import Routes from './routes' 
import Relay from 'react-relay' 
import useRelay from 'react-router-relay' 
import {RelayNetworkLayer, urlMiddleware} from 'react-relay-network-layer' 
import {relayApi} from './config/endpoints' 
import auth from './utils/auth' 

const createHeaders =() => { 
    let idToken = auth.getToken() 
    if (idToken) { 
    return { 
     'Authorization': `Bearer ${idToken}` 
    } 
    } else { 
    return {} 
    } 
} 

Relay.injectNetworkLayer(
    new RelayNetworkLayer([ 
    urlMiddleware({url: (req) => relayApi,}), 
     next => req => { 
      req.headers = { 
      ...req.headers, 
      ...createHeaders() 
      } 
      return next(req) 
     }, 
    ],{disableBatchQuery: true}) 
) 

ReactDOM.render(
    <Router 
    environment={Relay.Store} 
    render={applyRouterMiddleware(useRelay)} 
    history={browserHistory} 
    routes={Routes} 
    />, 
    document.getElementById('root') 
)

Duplicate question。

找到克里斯Mazzouchi的答案有幫助，雖然我不得不卸載並重新安裝下面的特定版本得到它的工作：

yarn remove react-relay react-relay-network-layer react-router-relay 
yarn add react-relay@0.10.0 react-relay-network-layer@1.3.9 react-router-relay@0.13.5
