Error: ENOSPC: System limit for number of file watchers reached, watch '/home/zox/Desktop/Angular/proba/node_modules/rxjs/_esm2015/internal/util/root.js.map' code example

Example 1: Error: ENOSPC: System limit for number of file watchers reached

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
# that modifies the file watch limit to max 524,288 which consume approx. 512MB Ram for 64bit.
# reduce that number to consume less memory.

# to see if that did it run
cat /proc/sys/fs/inotify/max_user_watches

# you should see
fs.inotify.max_user_watches=524288
