我想用thoughtbot 的波旁威士忌和整洁的方式制作我的octopress 博客模板。我找不到任何从头开始涵盖 octopress（或其根，jekyll）主题的文档。所以，我决定自定义 octopress 默认主题。
我已经添加了相关的宝石Gemfile：
gem 'compass', '~> 1.0.0.rc.1' # to make compass work with sass 3.3
gem 'sass', '~> 3.3' # unnecessary but better to be placed hier
gem 'bourbon'
gem 'refills'
gem 'neat'
gem 'bitters'
然后，我在.themes路径下复制了默认主题，例如：
ls .themes/classic .themes/bourtlen # so, new theme name is bourtlen :)
我已将sass文件夹设为bourtlen空。然后在里面sass，我跑了：
bourbon install
所有波旁威士忌资产现在都在sass. 然后，我在下面添加screen.scss了sass：
@import 'compass';
@import 'bourbon/bourbon';
@import 'base/base';
@import 'neat/neat';
@import 'custom/custom'; # for customization, it's also created in sass folder as _custom.scss
毕竟，我已经安装了我的新生主题，但是当我点击命令生成站点时，我收到了这些警告和错误：

站点毕竟在本地运行，但由于（可能）这些错误和警告而没有效果。我想知道缺少什么。
