react-native Unable to resolve module 'warnOnce'

my English is little rusty, I'm sorry for that.

I have an error at the moment when I am starting react-native project on the iOS Simulator.

To rule out any conflict with my code, I started a new project

react-native init demo

react-native start 

react-native run-ios --simulator="iPhone 6"

Now is when i get the message error

Loading dependency graph, done.
error: bundling failed: Error: Unable to resolve module `warnOnce` from `node_modules/react-native/Libraries/react-native/react-native-implementation.js`: warnOnce could not be found within the project.

If you are sure the module exists, try these steps:
 1. Clear watchman watches: watchman watch-del-all
 2. Delete node_modules: rm -rf node_modules and run yarn install
 3. Reset Metro's cache: yarn start --reset-cache
 4. Remove the cache: rm -rf /tmp/metro-*
