按照这些说明使用Bundler运行Foundation的多个版本后，我成功创建了一个依赖于3.2.5的新项目。
以下是我的Gemfile：
source "https://rubygems.org"
gem "zurb-foundation", "3.2.5"
gem "compass"
我接着运行了bundle exec compass create . -r zurb-foundation --using foundation，它创建了我的Gemfile.lock文件：
GEM

但是 - 在尝试使用Codekit编译时，我遇到了以下问题：
Compass was unable to compile one or more files in the project:
error app.scss (Line 1 of _settings.scss: File to import not found or unreadable: foundation/common/ratios.
Load paths:
/Users/chester/Sites/f3.2.5test/sass
/Library/Ruby/Gems/1.8/gems/compass-0.12.2/frameworks/blueprint/stylesheets

/Library/Ruby/Gems/1.8/gems/zurb-foundation-4.0.5/scss
Compass::SpriteImporter)
overwrite app.css
(This action was triggered by a change to _settings.scss)
从外观上看，似乎仍在尝试从4.0.5获取某些内容。顺便提一下，我在尝试升级Foundation时收到了这条消息：
sudo gem update zurb-foundation

我能够创建/使用F4项目，但出现了某些F3项目仍然引用F4的问题（并出现了那些难以理解的错误）。非常感谢任何帮助。谢谢！
更新
这似乎是Codekit的问题——因为使用标准的“bundle exec compass watch”似乎可以正常工作。开发者没有回复我对此提出的问题——所以任何其他“已经”成功的人分享他们的见解将会让我感激不尽。谢谢。
