When creating a new react native project using the standard react-native init MyApp and running react-native run-ios for the first time I\'m seeing
react-native init MyApp
react-native run-ios
Try to update your npm version first
npm update -g npm@version or sudo npm -gf update npm@version
npm update -g npm@version
sudo npm -gf update npm@version
and then just add the babel runtime at your react native project
npm add @babel/runtime
