指南針在CSS中輸出回溯，而不是生成CSS。我對Windows 7和Ubuntu Linux 12.0有相同的結果我已經在Compass 0.12.2和0.11.1上測試過了，我在Ruby 1.9.3p385和1.9.1P378上測試了這個結果。紅寶石指南針在CSS中輸出回溯
我config.rb文件：
# Require any additional compass plugins here.
http_path = "/n4"
css_dir = "css"
sass_dir = "sass"
images_dir = "images"
javascripts_dir = "js"
# relative_assets = true
output_style = :compact #or :nested, :expanded, :compressed
line_comments = false
# Disable these for production (also when viewing in IE6; will cause unnecessary display errors)
# sass_options = {:debug_info => true}
的CSS文件的內容：
/*
