Javascript grunt sass和grunt contrib watch似乎并没有像预期的那样协同工作

我使用grunt sass和grunt watch来编译和缩小我的代码

grunt.config('watch', {
    scripts: {
      files: ['<%= project.src.js.directory %>/*.js'],
      tasks: ['concat:scripts', 'uglify:compile']
    },
    styles: {
      files: [
        '<%= project.src.css.directory %>/**/*.scss'
      ],
      tasks: ['sass:compile', 'cssmin:minify']
    }
});

有关信息，my package.json如下所示：

{
  ...
  "devDependencies": {
    "grunt": "~0.4.5",
    "time-grunt": "~1.3.0",
    "load-grunt-tasks": "~3.5.0",
    "grunt-contrib-concat": "~0.5.1",
    "grunt-contrib-uglify": "~0.9.2",
    "grunt-contrib-watch": "~0.6.1",
    "grunt-sass": "~1.1.0",
    "grunt-contrib-cssmin": "~1.0.1"
  }
}

您可以包括

sass:compile

和

cssmin:minify

任务吗？或者更好，你能包括你的整个Gruntfile.js吗？我添加了我的Gruntfile.js！谢谢。
