de acordo com a documentação eu instalei todos oficiais create-react-native-app e suas dependências.
aqui está minha tela de saída após o início do npm
gd@gd:~/Desktop$ cd testing7/
gd@gd:~/Desktop/testing7$ npm start

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

execute os seguintes comandos ou crie arquivos bash com os seguintes conteúdos e
executado como bash yourfilename.sh

watchman shutdown-server
sudo pkill -9 -x fseventsd
echo fs.inotify.max_user_instances=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
echo fs.inotify.max_queued_events=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
Tente estes dois comandos
'watchman watch-del-all'
'watchman shutdown-server'
tente este comando:
echo 256 | sudo tee -a /proc/sys/fs/inotify/max_user_instances
echo 32768 | sudo tee -a /proc/sys/fs/inotify/max_queued_events
echo 65536 | sudo tee -a /proc/sys/fs/inotify/max_user_watches
