javascript - Grunt 在 Grunt + Sass 设置中创建 .tmp 文件夹

Question

这是我的设置:

  sass: {
    files: {
      'styles/main.css': 'styles/main.scss'
    }
  },

  grunt.loadNpmTasks('grunt-contrib-sass');
  grunt.loadNpmTasks('grunt-contrib-watch');

  grunt.registerTask('default', [
    'newer:jshint',
    'watch',
    'test',
    'build'
  ])

  watch: {
    styles: {
        files: ['<%= yeoman.app %>/styles/{,*/}*.css', '<%= yeoman.app %>/styles/{,*/}*.scss'],
        tasks: ['newer:copy:styles', 'autoprefixer', 'sass']
    }
  }

出于某种原因，Grunt 将 CSS 文件保存在 .temp 文件夹中:

>> File "app\styles\main.scss" changed.
Running "newer:copy:styles" (newer) task
No newer files to process.

Running "autoprefixer:server" (autoprefixer) task
Autoprefixer's process() method is deprecated and will removed in next major release. Use postcss([autoprefixer]).process() instead
File .tmp/styles/main.css created.

Running "autoprefixer:dist" (autoprefixer) task
Autoprefixer's process() method is deprecated and will removed in next major release. Use postcss([autoprefixer]).process() instead
File .tmp/styles/main.css created.

Running "sass:files" (sass) task

我希望它保存在与 main.scss 文件 styles 相同的文件夹中。我做错了什么？

编辑:

自动前缀任务:

autoprefixer: {
  options: {
    browsers: ['last 1 version']
  },
  server: {
    options: {
      map: true,
    },
    files: [{
      expand: true,
      cwd: '.tmp/styles/',
      src: '{,*/}*.css',
      dest: '.tmp/styles/'
    }]
  },
  dist: {
    files: [{
      expand: true,
      cwd: '.tmp/styles/',
      src: '{,*/}*.css',
      dest: '.tmp/styles/'
    }]
  }
},

我认为这是导致问题的原因？

仍然，没有运气。这是我的整个 grunt 文件:

Answer 1

从您的 grunt 文件看来，您的构建链似乎已设置为在文件夹 .tmp 中生成最终文件(Angular Javascript、自动前缀 CSS)。 并且您的快速服务器正在提供来自它们的文件，这是一致的。

这是一种非常合理的工作方式:您不想将生成的文件与您的实际源文件混合，这使得分发的重新生成和打包变得棘手。

所以我建议回到那种方式 - 或者可能澄清是什么让你想摆脱这种方式？

关于您最初的问题，在您的文件中搜索“.tmp”会显示 copy:styles 是将源 CSS 复制到 .tmp 的任务，以便自动前缀对它们进行处理。
