Error when running watchman

Question

When I run react-native start, I am getting the following message

Error: A non-recoverable condition has triggered. Watchman needs your help! The trigg

Answer 1

Just run these commands in terminal:

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
watchman shutdown-server  

Other Way make Script in package.json

"scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest",
    "flow": "flow",
    "flow-stop": "flow stop",
    "watch-need-help": "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 && watchman shutdown-server"
  },

Run following command on Terminal in project directory

npm run watch-need-help
