After copying the settings file, when i run ```grunt``` I keep getting the error @import util is not found. 

 gruntfile.js

        sass: {
            dist: {
                options: {
                    outputStyle: 'expanded',
                    sourceMap: false,
                    includePaths: ['bower_components/foundation-sites/scss']
                },
                files: {
                    'css/foundation.css': 'scss/foundation.scss',
                    'css/main.css': 'scss/main.scss',
                }
            }
        }, // sass

foundation.scss

@import 'includes/settings';
@import 'foundation';
@include foundation-everything;
