错误添加模块：提供此模块的几个文件

Question

我正在尝试使用命令yarn add react-native-navigation-drawer在我的项目上安装react-native-navigation-drawer。

执行命令后，我运行应用程序时出现错误。

/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 

我对反应原生很新。你能帮我解决这个问题吗？ 编辑：

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

jest-haste-map: @providesModule naming collision:
