I am trying to run my React Native Android project on macOS using:

npx react-native run-android

But the build fails with this error: error Failed to install the app. Command failed with Unknown system error -8: ./gradlew app:installDebug -PreactNativeDevServerPort=8081 spawn Unknown system error -8. info Run CLI with --verbose flag for more details.

enter image description here

The strange part is:

  • The project builds fine on Windows
  • It also builds successfully inside Android Studio on macOS
  • The error only happens when running npx react-native run-android

What I already checked

  • SDK paths are correct
  • Permissions are correct
  • No quarantine flags on gradlew or node_modules
  • I recently upgraded the project

My environment

React Native: 0.77.3
Node: 20.15.1
OpenJDK: 17.0.14 (LTS)
macOS

Question

What can cause Unknown system error -8 when spawning ./gradlew in React Native CLI, and how can I fix this? Why does Android Studio build successfully, but the CLI fails?
