Steps to reproduce issue

Ubuntu default (or on my system) value for watch file is

cat /proc/sys/fs/inotify/max_user_watches
8129

When I set number of max watch file as 100000 then there was no error.

sudo sysctl -w fs.inotify.max_user_watches=100000

So to reproduce, check in system the inotify value of max_user_watches and change to less number.

Thank you for such a wonderful package I use this in every project.
