"Visual Studio Code is unable to watch for file changes in this large workspace" (error ENOSPC)

코드 작성 중 vsCode 동작이 자꾸 멈추면서 위와 같은 에러가 떴음.
vsCode 안내에 따르면 다음과 같이 해결됨.

The current limit can be viewed by running:

cat /proc/sys/fs/inotify/max_user_watches

The limit can be increased to its maximum by editing /etc/sysctl.conf

sudo sysctl fs.inotify.max_user_watches=524288
sudo sysctl -p

The new value can then be loaded in by running sudo sysctl -p.
