Run the below command to avoid ENOSPC:

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

For Arch Linux add this line to /etc/sysctl.d/99-sysctl.conf:

fs.inotify.max_user_watches=524288

Then execute:

sysctl --system

This will also persist across reboots. Technical Details Source
