Laravel 9 switched to vite now ENOSPC limit of file watchers reached

Question

I'd been using Laravel 9 since the early version with Jetstream.

After having followed the vite upgrade guide I ran the command

npm run dev

And I got the following error stack trace:

VITE v3.0.7  ready in 282 ms

How do I fix it?

What am I missing?

Solved

Looks like it's working now.

What I did was to restart my computer and now npm run dev is working as it should and throws no errors:

16:25:13 [vite] page reload resources/views/components/layouts/pages.blade.php (x3)

Answer 1

I've hit this problem in the past, and used this answer to fix the problem.

In your case, rebooting may have fixed the problem temporarily, as not all the programs using file watchers will have re-started when your computer turned back on.

At some point, you'll hit the same issue if you haven't changed your environment. For a more permanent fix, try this from the answer I linked above:

If you are using Linux, your project is hitting your system's file watchers limit

To fix this, on your terminal, try:

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