Grunt显示此错误警告：OptionParser :: InvalidOption：无效选项： - source-map使用--trace进行回溯。使用--force继续

Question

我试图在grunt.js文件中删除sourceMap，但是它显示了关于sourceMapEmbed的其他错误

sass: {
      options: {
        sourceMap: true,
        sourceMapEmbed: true,
        sourceMapContents: true,
        includePaths: ['bower_components']
      },
      dist: {
        files: [{
          expand: true,
          cwd: '<%= config.app %>/styles',
          src: ['*.{scss,sass}'],
          dest: '.tmp/styles',
          ext: '.css'
        }]
      },
      server: {
        files: [{
          expand: true,
          cwd: '<%= config.app %>/styles',
          src: ['*.{scss,sass}'],
          dest: '.tmp/styles',
          ext: '.css'
        }]
      }
    },
