node -v v6.2.2 npm -v 3.9.5 Env: Mac

I did fresh install as per instructions: i.e.,npm install -g gulp react-native-cli typings and npm install successful but after trying to start, it fails with following errors:

$ gulp start.ios

The error error TS5024: Compiler option 'declaration' requires a value of type boolean. is not a problem, it doesn't prevent the project to work fine.

Did you run gulp init before gulp start.ios ?

Closing, please re-open if it still happens after running gulp init before gulp start.ios
