錯誤添加模塊：提供此模塊的幾個文件

Question

我正在嘗試使用命令yarn add react-native-navigation-drawer在我的項目上安裝react-native-navigation-drawer。

執行命令後，我運行應用程序時出現錯誤。

/Users/reactProject/node_modules/react-native/package.json 
2017-10-16 15:10:43.664017+0200 mobilizeit[23431:100610] Ambiguous resolution: module '/Users/reactProject/index.ios.js' tries to require 'react-native', but there are several files providing this module. You can delete or fix them: 

/Users/reactProject/node_modules/react-native-drawer-layout-polyfill/node_modules/react-native/package.json 

/Users/reactProject/node_modules/react-native-navigation-drawer/node_modules/react-native/package.json 

/Users/reactProject/node_modules/react-native-tab-view/node_modules/react-native/package.json 

/Users/reactProject/node_modules/react-native/package.json 

我對反應原生很新。你能幫我解決這個問題嗎？ 編輯：

用命令yarn start --reset-cache我得到了很多，看起來像警告：

This warning is caused by a @providesModule declaration with the same name across two different files. 
jest-haste-map: @providesModule naming collision:
