gruntjs - cssmin给我 "Path must be a string. Received undefined"

Question

我的项目是一个非常基本的溜溜/角项目。我有以下cssmin配置。

    useminPrepare: {
      html: '<%= yeoman.app %>/index.html',
      options: {
        dest: '<%= yeoman.dist %>',
        flow: {
          html: {
            steps: {
              js: ['concat', 'uglifyjs'],
              css: ['cssmin']
            },
            post: {}
          }
        }
      }
    },
...
    cssmin: {
      dist: {
        files: {
          '<%= yeoman.dist %>/styles/main.css': [
            '.tmp/styles/{,*/}*.css'
          ]
        }
      }
    },
...
  grunt.registerTask('build', [
    'clean:dist',
    'wiredep',
    'useminPrepare',
    'concurrent:dist',
    'autoprefixer',
    'concat',
    'ngAnnotate',
    'copy:dist',
    'cdnify',
    'cssmin',
    'uglify',
    'filerev',
    'usemin',
    'htmlmin'
  ]);

当我运行grunt build时，出现以下错误:

Running "cssmin:generated" (cssmin) task
Warning: Path must be a string. Received undefined Use --force to continue.

Aborted due to warnings.

autoprefixer:server   3.3s 
ngAnnotate:dist       3.6s  
cdnify:dist          10.7s  
cssmin:dist          888ms  
Total 34.6s

我在其他帖子上看到了此错误，但是在cssmin中却没有。我已经将package.json中的库升级到最新版本，这可能是原因。

该项目一次 build 良好。我无法确定缺少什么路径。有人知道我想念的那条路吗？
