Error: ENOSPC: System limit for number of file watchers reached angular

Question

I am getting this error while doing my Angular 10 project.

Error from chokidar (/myProject): Error: ENOSPC: System limit for number of file watchers reached, watch '/myProject/tsconfig.spec.json'

Is there a method to resolve this error?

Looks like you got too many file watchers running? – Dominik Dec 15 '20 at 04:53 — Dominik, Dec 15 '20 at 04:53
Can I do something to shut them down? – MikhilMC Dec 15 '20 at 05:45 — MikhilMC, Dec 15 '20 at 05:45

You're running into a kernel limit with your inotify watchers. You can run this to fix it for the current boot,

sudo sysctl -w fs.inotify.max_user_watches=524288

You can run this to fix it for future boots,

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

I found this post and helped me to solve that problem. All you have to do is change the max_user_watches

I got this in vs code when doing ssh. I think the problem was that vs code was watching all the files in my node_modules folder. To solve this in vs code I went to:

File > Preferences > Settings, and then to the little paper icon at the top of the settings page. This takes you to the settings.json file vs code uses. Then I added this to the settings file and it solved the problem:

"files.watcherExclude": {
    "**/.git/objects/**": true,
    "**/.git/subtree-cache/**": true,
    "**/node_modules/**": true,
    "**/samples": true
},

This is the solution to take. – sg28 Apr 27 '22 at 23:50

Use below

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

To increase the number of watches by your system

# insert the new value into the system config

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

# check new value was applied

cat /proc/sys/fs/inotify/max_user_watches

I got this error in VS Code and checked that already had the files.watcherExclude options listed here. I found some alternatives to avoid this error, these may be helpful if you prefer not to increase the max-user-watches value.

Abstain from start many servers at the same time. Start only one Angular server at a time.
Abstain from open many folders at the same time in VSCode. If there is only one project, try opening a sub folder to reduce watches. (I started one server and opened two projects and the error showed up minutes later).
Avoid using VSCode terminal to start the Angular server, because it may be slower than the Linux terminal.
If the error is still appearing, and restarting VSCode with the above suggestions does not work, try restarting your machine to kill possible useless processes.

I hope it helps.
