React Native Fix Unable to start server

Ketika mencoba React Native saya mendapati error Unable to start server

{12:46}~/Projects/js/HelloWorldRN ➭ npm start  

> HelloWorldRN@0.1.0 start /home/linuxluv/Projects/js/HelloWorldRN
> react-native-scripts start

12:56:52: Unable to start server
  See https://git.io/v5vcn for more information, either install watchman or run the following snippet:
    sudo sysctl -w fs.inotify.max_user_instances=1024
    sudo sysctl -w fs.inotify.max_user_watches=12288
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! HelloWorldRN@0.1.0 start: `react-native-scripts start`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the HelloWorldRN@0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/linuxluv/.npm/_logs/2018-04-09T05_56_52_919Z-debug.log

Untukmengatasi masalah tersebut, eksekusi perintah berikut
sudo sysctl -w fs.inotify.max_user_instances=1024
sudo sysctl -w fs.inotify.max_user_watches=12288

Setelah menjalankan dua baris perintah tersebut, error Unable to start server berhasil diatasi.

Sebagai informasi versi npm 5.6.0, dan nodejs yang saya gunakan 8.11.1.
