Запуск приложения ReactNative на Android эмуляторе

Пытаюсь запустить на эмуляторе ReactNative приложение. Сделал вроде бы все по инструкции: https://reactnative.dev/docs/environment-setup , инициализировал проект: npx react-native init AwesomeProject, запустил его: npx react-native start, он запустился (пишет Welcome to React Native!). После чего пытаюсь во втором окне терминала запустить на эмуляторе с помощью команды: npx react-native run-android (до этого запустил Android эмулятор через AVM Menedger), но ругается и выдает ошибку:

error Failed to install the app. Make sure you have an Android emulator running or a device connected. Run CLI with --verbose flag for more details.
Error: Command failed: ./gradlew app:installDebug -PreactNativeDevServerPort=8081

И до этого еще пишет:

error Failed to launch emulator. Reason: No emulators found as an output of `emulator -list-avds`.
warn Please launch an emulator manually or connect a device. Otherwise app may fail to launch.
