从http://mwmanning.com/2011/11/29/Run-Your-Jekyll-Site-On-Heroku.html上的教程开始工作。当我尝试推送到 heroku 时，我在输出中收到“构建失败”消息。
Heroku 日志显示

Gemfile 和 Gemfile.lock 都显示thin 已安装。
source :rubygems
gem 'jekyll'
gem 'rdiscount'
gem 'rack-jekyll'
gem 'thin'
gem 'RedCloth'
命令bundle exec thin start在本地工作，并bundle show thin显示 Thin 是专门为当前 gemset 安装的。
我不明白为什么heroku仍然说瘦不见了？
