Podfile.lock manquant lors de l'exécution initiale de run-ios natif de React

Je configure IOS dev pour React Native (0.61) app qui a la version Android Android). Ce que j'ai fait consistait à copier src des composants et le fichier package.json après la configuration de l'environnement natif React en suivant la publication en ligne (outil de ligne de commande xcode installé 10.2). Mais le lancement de run-ios a échoué:

$ react-native run-ios
error Could not find "Podfile.lock" at /Users/mine/Documents/code/js/emps_fe6/ios/Podfile.lock. Did you run "pod install" in iOS directory?
error Could not find the following native modules: RNCAsyncStorage, RNDeviceInfo, RNGestureHandler, RNKeychain, BVLinearGradient, RNLocalize, RNReanimated, RNVectorIcons, react-native-video. Did you forget to run "pod install" ?

Voici la sortie des informations natives de react:

Voici le package.json:

    "xcode": "^2.0.0"
  },

Dans le message d'erreur, il a mentionné plusieurs modules manquants. Mais ces modules ont été installés comme indiqué dans le package.json. Je ne suis pas sûr de la signification du message d'erreur. J'ai également installé le simctl mais scrum simctl ne peut toujours pas le trouver. J'utilise VS Code comme IDE.

METTRE À JOUR:

a créé un Podfile.lock sous/ios, l'erreur devient lorsque run-ios:

error Cannot read property 'SPEC CHECKSUMS' of undefined. Run CLI with --verbose flag for more details.
TypeError: Cannot read property 'SPEC CHECKSUMS' of undefined

Étape 1:

Sudo gem install cocoapods

Étape 2:

cd ios && pod install && cd ../ && react-native run-ios

Si vous obtenez toujours une erreur lors de l'installation des modules, continuez les étapes ci-dessous.

Étape 3: mettez cela dans la console ->

xcrun -k --sdk iphoneos --show-sdk-path

si la réponse est

xcrun:_ error: SDK "iphoneos" cannot be located
xcrun: error: SDK "iphoneos" cannot be located
xcrun: error: unable to lookup item 'Path' in SDK 'iphoneos'

puis mettez ceci:

Sudo xcode-select --switch /Applications/Xcode.app

Puis réinstallez le pod
