Sass (Ruby CSS压缩器) Windows上的绝对路径参数

Question

我使用sass (来自haml-edge)来处理css文件，它在作为参数的绝对路径上崩溃：

K:\sass>sass.bat k:/sass/css/*.scss k:/sass/css/*.css --trace
d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/lib/sass/files.rb:23:in `read': No such file or directory - k
 (Errno::ENOENT)
    from d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/lib/sass/files.rb:23:in `tree_for'
    from d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/lib/sass/plugin.rb:220:in `update_stylesheet'
    from d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/lib/sass/plugin.rb:71:in `block in update_stylesheets'
    from d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/lib/sass/plugin.rb:71:in `each'
    from d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/lib/sass/plugin.rb:71:in `update_stylesheets'
    from d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/lib/haml/exec.rb:433:in `watch_or_update'
    from d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/lib/haml/exec.rb:349:in `process_result'
    from d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/lib/haml/exec.rb:41:in `parse'
    from d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/lib/haml/exec.rb:21:in `parse!'
    from d:/Programs/Ruby/lib/ruby/gems/1.9.1/gems/haml-edge-3.1.62/bin/sass:8:in `<top (required)>'
    from d:/Programs/Ruby/bin/sass:19:in `load'
    from d:/Programs/Ruby/bin/sass:19:in `<main>'

我能够通过在(Ruby\lib\ruby\gems\1.9.1\gems\haml-edge-3.1.62\lib\haml\exec.rb)：split_colon_path中注释一个条件来使其工作。

def split_colon_path(path)
  one, two = path.split(':', 2)
  if one && two && #### this part was commented #  ::Haml::Util.windows? &&
      one =~ /\A[A-Za-z]\Z/ && two =~ /\A[\/\\]/
    # If we're on Windows and we were passed a drive letter path,
    # don't split on that colon.
    one2, two = two.split(':', 2)
    one = one + ':' + one2
  end
  return one, two
end

有没有更好的平台检测解决方案？

Answer 1

这是一个已知的错误。这个问题在Sass的最新稳定版本中得到了修复，除非你使用的是mingw Ruby，在这种情况下，它将在下一个稳定版本(将于本周末发布)中得到修复。

Answer 2

在haml-edge 3.1.64中解决了问题。

对于记录，mingw被添加到{Ruby folder}\lib\ruby\gems\1.9.1\gems\haml-edge-3.1.64\lib\haml\util.rb中的host_os可能值

# Whether or not this is running on Windows.
#
# @return [Boolean]
def windows?
  RbConfig::CONFIG['host_os'] =~ /mswin|windows|mingw/i
end
