在过去的几个晚上，我一直在努力将我的第一个 rails 应用程序部署到 heroku，并且正在努力弄清楚如何解决这个问题。

我使用 Michael Hartl 的教程 (http://ruby.railstutorial.org/chapters/beginning#sec-deploying) 来确保我在 Cedar Stack 上设置了我的应用程序。

根据 Heroku 教程，我使用“瘦”作为服务器。

我已经阅读了一堆帖子并使用以下方法预编译了我的资产：

heroku run bundle exec rake assets:precompile bundle exec rake assets:precompile

我还迁移了我的数据库。

我的应用程序在我的本地主机上运行。

这是我的宝石文件：

source 'https://rubygems.org'

gem 'rails', '3.2.8'
gem 'bootstrap-sass', '2.0.0'
gem 'bcrypt-ruby'
gem 'thin'

group :development, :test do
  gem 'rspec-rails'
end

group :development do
  gem 'sqlite3'
end

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :production do
  gem 'pg'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

group :test do
  gem 'capybara'
  gem 'factory_girl_rails'
end

这是我的heroku日志

这看起来像重要的部分：

ActionView::Template::Error (screen.css isn't precompiled):

好像这个线程会解决你的问题。

正如它所说：

On heroku server (readonly filesystem), If you want runtime compilation of css (its not recommended but you can do it), make sure you have done settings like below -

# inside config/application.rb
config.assets.enabled = true
config.assets.prefix = Rails.root.join('tmp/assets').to_s

# If you are using sass then keep gem outside of asset group
 gem 'sass-rails',   '3.1.4'

# inside config/environments/production.rb
config.assets.compile = true

我在这里找到了答案：blueprint css rails 3.1 help

据我所知，这似乎是使用 Blueprint CSS 框架的问题。也就是说，还有两个注意事项：

  1. 我从 application.html.erb 布局文件中注释掉了 <%= stylesheet_link_tag "screen", :media=>"screen"%> 代码。
  2. 我没有安装“rubyracer”gem。我安装它是因为它位于引用答案的配置文件中。我不知道它做了什么。
  3. URL 斜杠（“/”）现在在我有链接的地方再次出现。我的预感是它是我将不得不深入研究和调试的 CSS 文件之一。但是，我首先拥有 stylesheet_link_tag 的全部原因是因为我试图摆脱那些讨厌的斜线。最终，我决定部署更重要。

希望这对其他人有帮助！

这是我最终解决问题的方法。感谢那些把我推荐到别处的人，这样我就可以把它们放在一起。

首先，我将蓝图移至供应商目录。我认为这对解决方案并不重要，但感觉更干净。

编译问题：

这个线程：blueprint css rails 3.1 help真的很有帮助。我发现 Martin 和 Gary 的回答（第 2 和第 3 条）比选定的回答更有帮助。

我（个人）在编译时遇到问题的部分原因是我对蓝图文件进行了一些编辑，这意味着在部署之前需要再次编译它们。

这个线程：rails 3.1.0 ActionView::Template::Error (application.css is not precompiled)在这方面很有帮助。基本上，只需在上传到 heroku 之前运行“Bundle exec rake assets:precompile”。上传后我还运行“heroku run rake assets:precompile”。

我如何摆脱链接中的 URL 斜杠： URL 是 Blueprint/print.css 中这段代码的结果：

a:link, a:visited {background:transparent;font-weight:700;text-decoration:underline;}
a:link:after, a:visited:after {content:" (" attr(href) ")";font-size:90%;}

我通过注释掉该代码解决了这个问题。当然，更改文件后，您必须再次 rake assets:precompile。但是，这一切都奏效了！
