当我运行npm start或react-native start时，我收到以下警告：
jest-haste-map: @providesModule naming collision:
Duplicate module name: core-js
Paths: {path_to_project}/node_modules/react-native/node_modules/core-js/package.json collides with {path_to_project}/node_modules/react-native/node_modules/fbjs/node_modules/core-js/package.json
This warning is caused by a @providesModule declaration with the same name across two different files.
jest-haste-map: @providesModule naming collision:
Duplicate module name: base64-js
Paths: {path_to_project}/node_modules/react-native/node_modules/base64-js/package.json collides with {path_to_project}/node_modules/react-native/node_modules/simple-plist/node_modules/base64-js/package.json
This warning is caused by a @providesModule declaration with the same name across two different files.
这是我的包.json文件

我的开发环境是：
node: v6.11.2
npm: 3.10.10
os: macOS Sierra
我已经尝试了任何方法，例如更新RN版本，清除watchMan缓存，指定所有依赖项的版本，调整devDependencies的版本，如babel-jest的版本，但所有这些都不起作用。 我不知道出了什么问题，我需要帮助。 或者这是否是一个问题。
什么都值得赞赏！
您可能已经使用名称生成了项目，然后将package.json中的name属性更改为其他名称。
检查app.json和package.json文件，以查看应用程序的所有文件中是否具有相同的项目名称
