Twitter bootstrap 从grunt contrib sass切换到grunt sass后，编译时间相同。两者所用的时间与我使用Ruby时相同

我听说过要开快车。我从Ruby换成了Grunt。但无论我使用Ruby、grunt contrib sass、grunt sass哪种编译方法，速度都是一样的。编译引导SCS需要15秒

grunt.js： config.rb：

通过配置，您仍在使用Compass编译SCSS文件，grunt sass任务既没有配置也没有运行。由于Compass是基于Ruby的，并且仍在使用Ruby SASS预处理器，因此编译时间没有任何改进

是SASS编译器的C/C++实现，它完全消除了Ruby。在评论中提到Compass有很多Ruby依赖性，因此在可预见的将来不会移植到Libsass。因此，如果您严重依赖Compass混音器和函数，则必须坚持使用Ruby预处理器

如果您可以取消Compass，则可以通过以下配置使用grunt sass：

module.exports = function(grunt) {
  grunt.initConfig({
    watch: {
        src: {
            files: ['public_html/sass/*.scss'],
            tasks: ['sass:dev']
        },
        options: {
            livereload: true
        }
    },
    sass: {
        options: {
            sourceMap: true,
            outputStyle: 'expanded'
        },
        dev: {
          files: [{
            expand: true,
            src: ['public_html/sass/**/*.{scss,sass}'],
            dest: 'public_html/css/'
          }]
        }
    }
  });

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

# Require any additional compass plugins here.

# You can select your preferred output style here (can be overridden via the command line):
# output_style = :expanded or :nested or :compact or :compressed
# output_style = :expanded
environment = :development

# To enable relative paths to assets via compass helper functions. Uncomment:
relative_assets = true

# To disable debugging comments that display the original location of your selectors. Uncomment:
# line_comments = false
line_comments = true

sourcemap = true
sass_options = {:sourcemap => true}

# If you prefer the indented syntax, you might want to regenerate this
# project again passing --syntax sass, or you can uncomment this:
# preferred_syntax = :sass
# and then run:
# sass-convert -R --from scss --to sass sass scss && rm -rf sass && mv scss sass
