css - Grunt 构建不会创建 css 文件

Question

我是 Yeoman 和 Grunt 的新手。

在执行 Grunt 构建时，构建似乎成功结束，但未创建 dist/styles/*.css 文件。

从日志来看，样式似乎已编译为 .tmp/styles/(请参阅下面的“compass:dist”( compass )任务)，但并未复制或缩小为 dist/styles。这就是为什么“usemin:css” (usemin) 不归档文件的原因。 - 但这只是一个猜测。

我正在使用由 yeoman 生成的基本 Gruntfile.info(我在下面添加了它)我做的唯一改变是注释掉 cssmin 任务，因为假设要执行 same thing .

这是构建输出:

        { dest: '.tmp\\concat\\scripts\\modules.js',
          src:
           [ SOURCE ] } ] } }

  uglify:
  { generated:
   { files:

          src: [ '.tmp\\concat\\scripts\\scripts.js' ] },

grunt.registerTask('build', [

    'bower-install',
    'useminPrepare',
    'concurrent:dist',
    'autoprefixer',
    'concat',

    'cdnify',
//    'cssmin',
    'uglify',
    'rev',
    'usemin',
    'htmlmin'
  ]);

干杯!

您的 HTML 中可能有问题，您可能忘记为 grunt 任务添加注释。

<!-- build:css(.) styles/vendor.css -->
<!-- bower:css -->
<link rel="stylesheet" href="bower_components/bootstrap/dist/css/bootstrap.css" />
<!-- endbower -->
<!-- endbuild -->
