Error when running watchman

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

Error: A non-recoverable condition has triggered. Watchman needs your help! The triggering condition was at timestamp=1489123194: inotify-add-watch(/var/www/html/eventManager/android/app/src/main/res/mipmap-mdpi) -> 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.

echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_watches && echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_queued_events && echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_instances && watchman shutdown-server && sudo sysctl -p

This command should resolve this error.

i faced the same problem even after reinstalling watchman using homebrew: after deleting the pid, log and sock files, the following steps worked for me:

  • touch pid && touch log && touch sock
  • watchman --foreground --logfile=/dev/stdout
  • Allowed accessibility permissions : sudo chmod 700 /usr/local -closed all terminals and re-runned my commands. That should help.

You can solve it by trying one of the below solutions:

first pass hit line of code in your terminal and test it :

echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_watches  && echo 999999 | sudo tee -a  /proc/sys/fs/inotify/max_queued_events && echo 999999 | sudo tee  -a /proc/sys/fs/inotify/max_user_instances && watchman  shutdown-server

or try to use "react-native run-android" or "run-ios" in the root of your project and then (in other terminal) "react-native start"

otherwise perhaps the debugger page was left open from previous sessions. Closing the tab completely and then opening the debugger in a new tab solved the issue.

if none of the above solution doesn't work with you try to restart your PC

Increase inotify limit to increase the limit on the number of files you can monitor.

$ echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf
$ sudo sysctl -p

Please go through this for more info

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
