我今天一直在努力弄清楚为什么我的rails应用程序在heroku上崩溃了。
以下是heroku日志的输出：

这是我的宝石文件：

gem "compass-rails", ">= 1.0.3", :group => :assets
gem "zurb-foundation", ">= 3.0.9", :group => :assets
gem "simple_form", ">= 2.0.2"
这是我的repo
我正在使用devise，foundation.zurb和其他一些东西。这是我的第一个rails应用程序，所以也许有一些重要信息我忘了告诉你们。任何帮助是极大的赞赏！请注意，我一直在改变左侧和中间位置以尝试修复此问题，因此请注意，我的来自pastie的gemfile与repo中的gemfile不同。我在这里粘贴的是我正在尝试使用的那个。
如果我能提供更多信息，请告诉我。
更新::::::::::::::::::::::::::::::::
我已经改变了我的gemfile：
source 'https://rubygems.org'
gem 'rails', '3.2.8'
#gem 'thin', '1.2.8'
gem 'devise'
group :production do
gem 'pg'
end
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
gem "compass-rails", ">= 1.0.3", :group => :assets
gem "zurb-foundation", ">= 3.0.9", :group => :assets
gem "simple_form", ">= 2.0.2"
现在它没有崩溃，但我正在点击500.html文件

答案 0 :(得分：8)
从日志中读取：
/app/vendor/bundle/ruby/1.9.1/gems/bundler-1.2.0/lib/bundler/rubygems_integration.rb:147:in
block in replace_gem': Please install the postgresql adapter:宝石 安装activerecord-postgresql-adapter`（pg不是。的一部分 束。将它添加到Gemfile。）（LoadError）
Heroku使用postgres连接到数据库（而不是sqlite），因此添加包含postgres gem的生产组
group :production do
gem 'pg'
end
这告诉bundler在生产时，安装pg gem（Heroku想要的）。
更新
第二个问题。再次从日志中获取：

这是sass文件：foundation_and_overrides.scss。首先，后缀不在asset-pipeline form中。此外，在该文件中，导入指的是丢失的文件。
TL; DR：花一些时间阅读输出日志！如果失败，大多数事情会在那里抱怨;）
