Gruntjs - 在哪里生成'来自?

标签: gruntjs yeoman grunt-contrib-cssmin

我碰巧碰到了这个并且坚持想出来。 我有这个笨拙的任务,名为build,如下,

grunt.registerTask('build', [
    'clean:dist',
    'wiredep',
    'useminPrepare',
    'concurrent:dist',
    'postcss',
    'ngtemplates',
    'concat',
    'ngAnnotate',
    'copy:dist',
    'cdnify',
    'cssmin',
    'uglify',
    'filerev',
    'usemin',
    'htmlmin'
]);

现在,在cssmin阶段,它总是抛出这样的错误,

Running "cssmin:dist" (cssmin) task
>> 1 file created. 365.26 kB → 140.55 kB

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

Aborted due to warnings.

但是,我的cssmin任务没有任何:generated路径。在这里,

cssmin: {
  dist: {
    files: {
      '<%= yeoman.dist %>/styles/main.css': [
        '<%= yeoman.app %>/styles/{,*/}*.css'
      ]
    }
  }
},

如果我运行cssmin:dist,它可以解决问题。但我很想找到这条:generated路径的来源。由于我目前正在修复所有依赖项以进行缩小和编译,因此我不想错过这条:generated路径实际上是我正在寻找的路径。
