      bowerDir: './bower_components'
  };
  
  gulp.task('css', function () {
      return gulp.src(config.sassPath + '/style.scss')
          .pipe(sass({
          loadPath: [
              './resources/sass',
          config.bowerDir + '/bootstrap-sass/assets/stylesheets',
          config.bowerDir + '/font-awesome/scss', ]
