'installDebug'はルートプロジェクトに見つかりません 'android' React Native

アンドロイドシミュレータでプロジェクトを実行しようとしています。私はreact-native run-androidを実行すると、私は次のように取得しています：'installDebug'はルートプロジェクトに見つかりません 'android' React Native

FAILURE: Build failed with an exception. 

* What went wrong: Task 'installDebug' not found in root project 'android'. 

* Try: Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. 

BUILD FAILED

私は./gradlew tasksを実行した場合、私は得る：
