Gulp Error watch path ENOSPC in gaze.js or grunt.js

When running Gulp with code like this:

gulp.task('default', ['watch']);

gulp.task('watch', ['css', 'js'], function () {
gulp.watch(scssSrc, ['css']);
gulp.watch(jsSrc, ['js']);
gulp.watch(svgSpriteSrc + "**/*.svg", ['svg']);
});

gulp.task('css', function () { /*и т.д. */}
gulp.task('js', function () { /*и т.д. */}
gulp.task('svg', function () { /*и т.д. */}

An error may occur that prevents the process from starting:

When running in the background, the dynamic collection of saved data in Ubuntu 18.04 is set to max_user_watches .

The fact is that the fs.inotify.max_user_watches parameter in /etc/sysctl.conf is responsible for simultaneously reading a certain number of files. When it reaches its limit, gulp's work is terminated.

Found the cure here and here :

echo fs.inotify.max_user_watches=131072 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

As a result, by increasing the number of simultaneously viewed files, we achieve the work of Gulp.

Don't go overboard with max_user_watches.
