Javascript 我能'；不要让Grunt源地图在foundation press主题中工作

我在为npm包grunt sass获取源地图时遇到困难

这是我的Grunfile.js

这是不工作的部分

sourceMap:true，

第13行

module.exports = function(grunt) {
    var jsApp = [
    'js/app.js',
    'js/_*.js'
  ];

  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),


      sass: {
        options: {
            sourceMap: true,
            includePaths: ['bower_components/foundation/scss']
        },
        dist: {
            files: {
                'css/app.css': 'scss/app.scss'
                }
            }
        },


    autoprefixer: {
        dist: {
            files: {
                'css/app.css': 'css/app.css'
            }
        },
      watch: {
          styles: {
              files: ['css/app.css'],
              tasks: ['autoprefixer']
          }
        }
      },

    copy: {
      scripts: {
        expand: true,
        cwd: 'bower_components/',
        src: '**/*.js',
        dest: 'js'
      },

      maps: {
        expand: true,
        cwd: 'bower_components/',
        src: '**/*.map',
        dest: 'js'
      }
    },

    uglify: {
      dist: {
        files: {
          'js/modernizr/modernizr.min.js': ['js/modernizr/modernizr.js']
        }
      }
    },

    concat: {
      options: {

        separator: ';'
      },
    dist: {
        src: [
          'js/foundation/js/foundation.min.js',
          'js/custom/*.js'
        ],

        dest: 'js/app.js'
      }

    }



  });

  grunt.loadNpmTasks('grunt-sass');
  grunt.loadNpmTasks('grunt-autoprefixer');
  grunt.loadNpmTasks('grunt-contrib-watch');
  grunt.loadNpmTasks('grunt-contrib-concat');
  grunt.loadNpmTasks('grunt-contrib-copy');
  grunt.loadNpmTasks('grunt-contrib-uglify');
  grunt.registerTask('default', ['sass']);
