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 trigg

Answer 1

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

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

updating

watchman

Answer 4

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

This One is Also Helpfull .

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

Answer 6

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
