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

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?

Solution 1:[1]

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

Error ENOSPC System limit for number of file watchers reached

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
},

Use below

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

To increase the number of watches by your system

Solution 5:[5]

# 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.
