Error: ENOSPC: System limit for number of file watchers reached

reason

cat /proc/sys/fs/inotify/max_user_watches

Watchers are part of the inotify Linux kernel subsystem1 that extend the filesystem to notice changes and report on those changes to applications listening for them

slove

1. run as production mode

2. set on vscode watcher’s ignore list ``` settings.json

“files.watcherExclude”: { “/.git/objects/”: true, “/.git/subtree-cache/”: true, “/node_modules//**”: true, “**/package-lock.json”: true, “**/yarn.lock”: true, “**/dist//”: true, “/vendor/*/”: true, “/dist_electron/”: true, },

3. increase temporary

sudo sysctl fs.inotify.max_user_watches=10000 sudo sysctl -p

4. increase forever

echo fs.inotify.max_user_watches=10000 | sudo tee -a /etc/sysctl.conf sudo sysctl -p ```
