Всякий раз, когда я запускаю response-native run-android , сохраняя работу эмулятора, я получаю эту ошибку. Реакция -родной Run-ios работает совершенно нормально.

Error: Command failed: ./gradlew app:installDebug -PreactNativeDevServerPort=8081 :ReactNative:Failed to parse React Native CLI configuration: groovy.json.JsonException: Unable to determine the current character, it is not a string, number, array, or object The current character read is 'E' with an int value of 69 Unable to determine the current character, it is not a string, number, array, or object line number 1 index number 0 Error: Invalid attribute nameLine: 16Column: 18Char: . at error (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/sax/lib/sax.js:651:10) at strictFail (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/sax/lib/sax.js:677:7) at SAXParser.write (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/sax/lib/sax.js:1313:13) at new XmlDocument (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/xmldoc/lib/xmldoc.js:261:15) at readManifest (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/@react-native-community/cli-platform-android/build/config/readManifest.js:38:10) at Object.projectConfig (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/@react-native-community/cli-platform-android/build/config/index.js:59:46) at Object.get project [as project] (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/react-native/node_modules/@react-native-community/cli/build/tools/config/index.js:114:50) at /Users/yashatreya/Desktop/Realyze/Realyze/node_modules/react-native/node_modules/@react-native-community/cli/build/commands/config/config.js:8:452 at Array.forEach ({amp}lt;anonymous{amp}gt;) at _objectSpread (/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/react-native/node_modules/@react-native-community/cli/build/commands/config/config.js:8:392) ^ FAILURE: Build failed with an exception. * Where: Script '/Users/yashatreya/Desktop/Realyze/Realyze/node_modules/@react-native-community/cli-platform-android/native_modules.gradle' line: 201 * What went wrong: A problem occurred evaluating script. {amp}gt; 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. * Get more help at https://help.gradle.org 

Как указано в сообщении об ошибке, я попытался запустить npm uninstall -g react-native react-native-cli но это не сработало.

Изначально я получал эту ошибку: ошибка сборки собственного кода: не удалось найти реализацию метода () для аргументов [jscFlavor] в проекте ‘: app’ типа org.gradle.api.Project, но теперь я получаю вышеуказанное.

Я думаю, что эта проблема только в более новой версии (0.61) У меня была такая же проблема, и я просто использовал старую версию (0.60.0)

  npx react-native init AwesomeProject --version 0.60.0
