리눅스는 사용자당 inotify 감시 개수에 상한(max_user_watches)이 있다1 — 모자라면 webpack 이 변경을 못 알아챈다2.

# `System limit for number of file watchers reached`

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

Footnotes

  1. inotify(7) - Linux manual page: “/proc/sys/fs/inotify/max_user_watches This specifies an upper limit on the number of watches that can be created per real user ID.” ↩

  2. Watch and WatchOptions | webpack: “Verify that you have enough available watchers in your system. If this value is too low, the file watcher in Webpack won’t recognize the changes” ↩
