Estou na primeira aula e assim que eu iniciei o projeto da esse erro.
BUILD FAILED in 5s
error Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup. Run CLI with --verbose flag for more details. Error: Command failed: gradlew.bat app:installDebug -PreactNativeDevServerPort=8081
Alguém sabe resolver sem ter que apagar e começar tudo do zero?
