Gulp Error: spawn EACCES

Hi guys,

I successfuly installed homestead on my machine recently and since then, everytime I try to run the gulp watch command, I run into this problem.

    Local: http://localhost:3000
    External: http://10.0.2.15:3000

          UI: http://localhost:3001

internal/child_process.js:298
    throw errnoException(err, 'spawn');
    ^

From my search around the web I found this answer, http://stackoverflow.com/questions/31005867/gulp-error-spawn-eacces but so far I don't seem to have any luck with it because I can't find where laravel keeps the server.js file for gulp.

Also here's an example of my gulpfile

elixir(function (mix) {

    mix.sass('app.scss', './public/css/style.css')
            .browserify([
                'homepage.js',
                'feed.js',
                'search.js'
            ], './public/js/script.js')
            .version(['css/style.css', 'js/script.js'])
            .browserSync({proxy: 'localhost:8000'});
});

Any help would be very appreciated.
