Android build error: expected buildTargetsCommandComponents command 'ninja' to exist

[dinesh-brilworks]

I am getting following error in my react native Android build,

Execution failed for task ':react-native-fast-openpgp:configureCMakeDebug[arm64-v8a]'.

[CXX1410] /Users/user/Developer/.../node_modules/react-native-fast-openpgp/android/.cxx/Debug/5v282i3v/arm64-v8a/android_gradle_build.json debug|arm64-v8a : expected buildTargetsCommandComponents command 'ninja' to exist

I do have ninja installed already.
