Error starting run-android -variant = release (Task 'installReleaseDebug' was not found in the root project 'gnosisapp'.)

Question

I have this error trying to make react-native run-android --variant=release

 Starting JS server... Running /home/sonic182/Android/platform-tools/adb -s ZY2232QD4K reverse tcp:8081 tcp:8081 Building and installing the app on the device (cd android && ./gradlew installReleaseDebug)... FAILURE: Build failed with an exception. * What went wrong: Task 'installReleaseDebug' not found in root project 'gnosisapp'. * 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 Total time: 7.779 secs Could not install the app on the device, read the error above for details. Make sure you have an Android emulator running or a device connected and have set up your Android development environment: https://facebook.imtqy.com/react-native/docs/android-setup.html (node:24877) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): TypeError: Cannot read property 'message' of undefined 

I finished Ubuntu 16.04, I took all the steps from here https://facebook.imtqy.com/react-native/docs/signed-apk-android.html to the testing phase, where I need to execute react-native run-android --variant=release

What could it be?: / Thanks

If you are using React Native 0.39.x, use this:

 react-native run-android --configuration=release
