erreur de gardien watch-native, après le démarrage de npm sous Ubuntu 17.10.

J'essaie de démarrer le projet de React-native sur Ubuntu, noeud, npm sont les dernières versions. Selon la documentation, j'ai installé tous les fichiers create-react-native-app officiels et leurs dépendances.

voici mon écran de sortie après le démarrage de npm

Gd@gd:~/Desktop$ cd testing7/
Gd@gd:~/Desktop/testing7$ npm start

> [email protected] start /home/Gd/Desktop/testing7
> react-native-scripts start

jest-haste-map: Watchman crawl failed. Retrying once with node crawler.
  Usually this happens when watchman isn't running. Create an empty `.watchmanconfig` file in your project's root folder or initialize a git or hg repository in your project.
  Error: Watchman error: A non-recoverable condition has triggered.  Watchman needs your help!
The triggering condition was at timestamp=1523075484: opendir(/home/Gd/Desktop/testing7/node_modules/metro/node_modules/ansi-regex) -> The user limit on the total number of inotify watches was reached; increase the fs.inotify.max_user_watches sysctl
All requests will continue to fail with this message until you resolve
the underlying problem.  You will find more information on fixing this at
