React-Native Run-Android Not Working After Upgrading

Question

I have recently upgraded my app's react-native version to 0.60, and want to run the app on an android emulator to see if everything is working as it should be. When I ran the command react-native run-android I get an error that says: error Failed to install the app. Make sure you have the Android development environment set up: https://facebook.github.io/react-native/docs/getting-started.html#android-development-environment . Run CLI with --verbose flag for more details. Error: Command failed: gradlew.bat app:installDebug -PreactNativeDevServerPort=8081

FAILURE: Build failed with an exception.

• What went wrong: Could not determine the dependencies of task ':app:preDebugBuild'.

  Could not resolve all task dependencies for configuration ':app:debugRuntimeClasspath'. What can I do to successfully run my app?

Answer 1

below these may clear the issue I guess;

• upgrade NODE and NPM if necessary (this solved my issue)
• gradle clean on android
• delete node modules and re-install npm (since on npm installation there should be no network interruption)
• make sure any of the packages are not linked properly.
• re-open terminal
