Erreur: impossible de déterminer le caractère actuel, il ne s'agit pas d'une chaîne, d'un nombre, d'un tableau ou d'un objet dans react-native pour android

Chaque fois que je lance run-android react-native tout en gardant l'émulateur en marche, j'obtiens cette erreur. run-ios natif de react fonctionne parfaitement.

Error: Command failed: ./gradlew app:installDebug -PreactNativeDevServerPort=8081

A problem occurred evaluating script.
> Failed to parse React Native CLI configuration. Expected running 'npx --quiet --no-install react-native config' command from '/Users/yashatreya/Desktop/Realyze/Realyze' directory to output valid JSON, but it didn't. This may be caused by npx resolving to a legacy global react-native binary. Please make sure to uninstall any global 'react-native' binaries: 'npm uninstall -g react-native react-native-cli' and try again

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Comme indiqué dans le message d'erreur, j'ai essayé de lancer npm uninstall -g react-native react-native-cli mais cela n'a pas fonctionné.

Au départ, j'obtenais cette erreur: erreur de construction native de réaction: impossible de trouver l'implémentation de la méthode () pour les arguments [jscFlavor] sur le projet ': app' de type org.gradle.api.Project mais maintenant j'obtiens ce qui précède.

SOLUTION 1 (travaillé pour moi)

La solution pour moi était de supprimer la ligne suivante

apply from: file("../../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesAppBuildGradle(project)

Assurez-vous de le retirer partout. J'avais cette ligne build.gradle (app) et aussi dans settings.gradle .

Après cela, exécutez à nouveau npx react-native run-android la console affichera la vraie erreur, corrigera l'erreur et remettra les lignes que vous avez supprimées.

Dans mon cas, l'erreur s'est produite parce que j'utilisais une ancienne version de Node et la deuxième fois.Il s'est produit que j'avais besoin de synchroniser à nouveau mon projet

SOLUTION 2

Supprimez les fichiers sur lesquels il a trouvé une erreur: "Le caractère actuellement lu est 'E' avec une valeur int de 69"

Suppression

app\build\intermediates\signing_config\debug\out\signing-config.json

travaillé pour les autres aussi.

SOLUTION 3

Mettez à jour @ react-native-community / cli vers la dernière version.

Bon codage!

Je pense que ce problème est uniquement dans la version la plus récente (0.61) J'ai eu le même problème et je viens d'utiliser l'ancienne version (0.60.0)

 npx react-native init AwesomeProject --version 0.60.0

Je viens de supprimer le dossier de construction dans Android et accédez au dossier Android, puis dans PowerShell tapé ./gradlew propre puis cd..=>npx react-native run-android
