Cuando intento instalar reaccionar nativo con el comandoreact-native init ProjectName

Me sale lo siguiente:

This will walk you through creating a new React Native project in C:\Users\Xegano\Documents\ProjectName
Installing react-native package from npm...

    throw err;

¿Por qué pasó esto? Solía funcionar antes, lo único que recuerdo que cambié es algunos paquetes del SDK Manager. ¿Será que?
