npm install:  grunt  , grunt-cli, grunt-contrib-coffee

$ npm install grunt-contrib-coffee --save-dev 

编辑:  Gruntfile.coffee: 

module.exports = (grunt) ->
  grunt.initConfig
    coffee:
      compile_multiple_files:
        options:
          bare: true
        files:
          # 1:1 的编译文件
          #'app/controllers/simulate_stocks.js': 'app/controllers/simulate_stocks.coffee'
          # 编译多个文件
          [
            expand: true
            flatten: true
            cwd: 'app/controllers/'
            src: ['*.coffee']
            dest: 'app/controllers/'
            ext: '.js'
          ]
      compile_home_js:
        options:
          bare: true
        files:
          # 把多个文件合并
          'app/controllers/home.js': [
            'app/controllers/home/home_market.coffee'
            'app/controllers/home/home_master.coffee'
            'app/controllers/home/home_me.coffee'
            'app/controllers/home/home_competition.coffee'
            'app/controllers/home/home_community.coffee'
            'app/controllers/home/home_version.coffee'
            'app/controllers/home/home_frame.coffee'
          ]
  #grunt.loadNpmTasks 'grunt-contrib-watch'
  grunt.loadNpmTasks 'grunt-contrib-coffee'

  grunt.registerTask 'default', [ 'coffee' ]

然后运行: $ grunt 

就会把 coffee的所有 子任务 (sub- tasks) 都依次运行了. 结果如下; 

$ grunt
Running "coffee:compile_multiple_files" (coffee) task
>> 53 files created.

Running "coffee:compile_home_js" (coffee) task
>> 1 files created.

Done, without errors.
