Question

我有一个反应堆本地项目，当我在Windows 10环境中启动react-native run-android时，它可以工作，但是在react-native run-ios MacOS环境中，我的捆绑终端给出了此错误，

    Loading dependency graph...(node:46534) UnhandledPromiseRejectionWarning: Error: jest-haste-map: Haste module naming collision:

我尝试了

删除所有node_modules
清除npm缓存
删除守卫
我创建了一个新项目，但它在我的项目中不起作用我的package.json这样 https://ybin.me/p/8941c752fb540ea5#AxqA/1Ckte5N2k8crVggkmQGiRQjP5VOAF/TIxRo4Dw=

Podfile

    # Uncomment the next line to define a global platform for your project
platform :ios, '9.0'

target 'mpp' do
 # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
 # use_frameworks!
 pod 'RNVectorIcons', :path => '../node_modules/react-native-vector-icons'
 pod 'RNI18n', :path => '../node_modules/react-native-i18n'

 # Pods for mpp

 target 'mppTests' do
   inherit! :search_paths
   # Pods for testing
 end

end

我遇到了同样的问题，可以通过以下命令来解决。

rm -rf ./node_modules && npm install
npm cache clean
npm start -- --reset-cache
