Fullcalendar Javascript error

I'm trying to import fullcalendar into a project, I'm using gulp to automate imports. But when I put the path to import fullcalendar I come across this error in the console:

  

fullcalendar.min.js: 6Uncaught TypeError: Can not read property 'push' of undefined

What could be the problem?

File% of gulp :

elixir(function(mix) {
    mix.styles([
        './resources/assets/css/app.css',
        './bower_components/fullcalendar/dist/fullcalendar.print.min.css',
        './bower_components/fullcalendar/dist/fullcalendar.min.css',
    ]);
    mix.scripts([
        './bower_components/jquery/dist/jquery.min.js',
        './node_modules/angular/angular.min.js',
        './resources/assets/js/mask.js',
        './bower_components/fullcalendar/dist/fullcalendar.min.js',
        './resources/assets/js/app.js'
    ]);
});
