Gulp watch not working Ubuntu 16.04 Laravel 5.3

Hello guys, I really need help with the following error:

'watch' errored after 29 ms [06:06:51] TypeError: Cannot read property 'indexOf' of undefined at /home/vagrant/votingmp/node_modules/globule/lib/globule.js:25:16 at Array.reduce (native) at processPatterns (/home/vagrant/votingmp/node_modules/globule/lib/globule.js:24:30) at Object.globule.find (/home/vagrant/votingmp/node_modules/globule/lib/globule.js:76:17) at Gaze.add (/home/vagrant/votingmp/node_modules/gaze/lib/gaze.js:174:19) at new Gaze (/home/vagrant/votingmp/node_modules/gaze/lib/gaze.js:74:10) at gaze (/home/vagrant/votingmp/node_modules/gaze/lib/gaze.js:86:10) at Object.module.exports [as watch] (/home/vagrant/votingmp/node_modules/glob-watcher/index.js:12:17) at Gulp.watch (/home/vagrant/votingmp/node_modules/gulp/index.js:40:14) at /home/vagrant/votingmp/node_modules/laravel-elixir/dist/tasks/recipes/watch.js:26:18

I can't seem to run gulp watch because of this error. I've updated by npm and node to the latest version, reinstall gulp-cli, did the npm cache clean, deleted the node_modules directory in my project and re run npm install but everything to no avail.

Please please help me on this.

Thanks!
