Gruntfile.js：

module.exports = function(grunt) {

    // Project configuration.
    grunt.initConfig({

        //Read the package.json (optional)
        pkg: grunt.file.readJSON('package.json'),

        // Metadata.
        meta: {
            basePath: '../',
            srcPath: '../assets/sass/',
            deployPath: '../assets/css/'
        },

        banner: '/*! <%= pkg.name %> - v<%= pkg.version %> - ' +
                '<%= grunt.template.today("yyyy-mm-dd") %>
' +
                '* Copyright (c) <%= grunt.template.today("yyyy") %> ',

        // Task configuration.
        sass: {
            dist: {
                files: {
                    '<%= meta.deployPath %>test.css': '<%= meta.srcPath %>test.scss'
                },
                options: {
                    sourcemap: 'true'
                }
            }
        },

                tasks: ['sass']
            }
        }
    });

    // These plugins provide necessary tasks.
    grunt.loadNpmTasks('grunt-contrib-sass');
