我正在使用Ruby版本1.9和Rails版本3.2
我已经将它包含在我的gemfile中（按照Micheal Hartl的书中的指示）
group :production do
gem 'pg', '0.15.1'
gem 'rails_12factor', '0.0.2'
end
我的repo在我的本地服务器上运行完美，我也可以在Heroku上成功部署它（因为它没有显示任何错误）但是当我尝试在Heroku上打开它时，它说发生了一些错误
Heroku链接：
Link to heroku application which isn't working
我的Github回购：
如何让我的rails应用程序在Heroku上运行？
修改
这是Heroku日志：

答案 0 :(得分：2)
首先将您的blueprint目录移至assets/stylesheets目录。
添加到environment / production.rb
config.assets.precompile += %w( blueprint/screen.css blueprint/print.css blueprint/ie.css custom.css)
如果您愿意，可以预先编译您的资产：
bundle exec rake assets:precompile RAILS_ENV=production
