javascript - 第一次运行 Grunt build 时出错

Question

我使用 Yeoman 创建了一个 angularJS 项目

使用 grunt serve 预览应用效果很好。服务器启动，我可以成功浏览我的页面。

当执行 grunt build 时，我得到了

Running "cdnify:dist" (cdnify) task
Going through dist/404.html, dist/index.html to update script refs
>> No "cssmin" targets found.
Warning: Task "cssmin" failed. Use --force to continue.

Aborted due to warnings.

我不知道如何修复或如何开始。我是否缺少某些配置？

现在的配置是:

  concat:
  { generated:
   { files:
      [ { dest: '.tmp\\concat\\scripts\\scripts.js',
          src:
           [ '{.tmp,app}\\cdnjs.cloudflare.com\\ajax\\libs\\noUiSlider\\5.0.0\\jquery.nouislider.min.js',
             .
             <MY_LIBRARIES>, 
             .] },
        { dest: '.tmp\\concat\\scripts\\modules.js',
          src:
           [ 'app\\scripts\\app.js',
             .
            <MY_SOURCE_FILES>, 
            . ] } ] } }

  uglify:
  { generated:
   { files:
      [ { dest: 'dist\\scripts\\scripts.js',
          src: [ '.tmp\\concat\\scripts\\scripts.js' ] },
        { dest: 'dist\\scripts\\modules.js',
          src: [ '.tmp\\concat\\scripts\\modules.js' ] } ] } }

  cssmin:
  {}

开箱即用的 Yeoman 配置需要进行一些调整。 cssmin 在被注释掉时是构建任务的一部分。由于稍后列出了“usemin”，我只是将其从任务中删除。
