I still do not know why, but in the newer versions of React Native its starting with babel-preset-react-native version 3.0.0 or 2.0.1.

These versions do not support some of the features we're used. To solve, just update to version 2.1.0. See facebook/react-native#15513

yarn add babel-preset-react-native@2.1.0

Or

npm install --save babel-preset-react-native@2.1.0
