Answer 1

The problem was Java 9. even though react-native site asks you to install Java SDK 8 or later , then 9 installation doesn't work for some reason. I uninstalled 9 and installed 8 and it worked like a charm

Answer 2

This normally happens when the JDK is not correctly installed or the JAVA_HOME has not properly been set. Make sure to export your JAVA_HOME path. and have a working JDK version running on your computer.
