我正在使用Windows 7來編譯名爲Prepros的應用程序.scss。 （http://alphapixels.com/prepros/）。我還將Gumby框架（http://gumbyframework.com/）下載到本地主機web服務器的文檔根目錄中。我的目標是與Prepros一起使用gumby框架。當我試圖用Prepros和Gumby編譯sass時，我該如何解決這個編譯錯誤？
當我試圖編譯SCSS文件，我收到以下錯誤：
Syntax error: Undefined operation: "power(golden_ratio(), 1) times 16px".
on line 52 of Z:/Ampps/www/Gumby-master/sass/extensions/modular-scale/stylesheets/_modular-scale.scss
from line 23 of Z:\Ampps\www\Gumby-master\sass\gumby.scss Use --trace for backtrace.
而且，如果它是有幫助的，這是該文件夾WWW \古比主內config.rb文件：
# Require any additional compass plugins here.
# Tell compass where to find local extensions
# If you followed directions and ran 'gem install modular-scale' comment the next two lines out:
extensions_dir = "sass/extensions"
Compass::Frameworks.register('modular-scale', :path => File.expand_path("# {extensions_dir}/modular-scale"))
# Uncomment these to use regular Ruby gems.
# require 'modular-scale'
# require 'sassy-math'
# Set this to the root of your project when deployed:
http_path = "/"
css_dir = "css"
sass_dir = "sass"
images_dir = "img"
# You can select your preferred output style here (can be overridden via the command line) :nested or :expanded or :compact or :compressed:
output_style = :compact
# 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
# 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
最後，我回顧this線程，但我沒有發現它有用。
