调试Heroku部署（500错误）

过去几个晚上我一直在将我的第一个rails应用程序部署到heroku，并且一直在努力弄清楚如何解决这个问题。调试Heroku部署（500错误）

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。

我读了一堆的职位，并使用预编译我的资产：

的Heroku运行包的exec耙资产：预编译捆绑高管耙资产：预编译

我也迁移我的数据库。

我的应用程序在我的本地主机上工作。

这里是我的Gemfile：

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

这里是我的Heroku的日志

以下是我最终如何解决问题的方法。感谢那些在别处提到我的人，以便我可以将它们放在一起。

首先，我将Blueprint移动到了供应商目录。我不认为这对解决方案至关重要，但它感觉更清洁。

编译问题：

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

为什么我在编译（个人）时遇到问题，部分原因是我对Blueprint文件进行了一些编辑，这意味着他们需要在部署之前再次编译。

此主题：rails 3.1.0 ActionView::Template::Error (application.css isn't precompiled)在这方面很有帮助。基本上，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”。

我是怎么摆脱URL的斜线在我的链接： 的网址是此代码蓝图/ print.css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%;}

我解决了注释掉的代码问题。当然，在更改文件之后，您必须重新分配资源：再次预编译。但是，这一切都工作！

这看起来像重要的部分：

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

好像this thread将解决您的问题。

，因为它说：

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

感谢您的回复！我昨晚看过那篇文章并试了一下。根据你的建议，我今天早上再试一次。仍然没有工作。尽管如此，我还没有尝试过你在这里提倡的运行时编译方法，因为我读过的所有内容都表明这样做会有相当大的性能损失。我错了吗？ – jflores

是的，有，但我找不到任何其他选项来解决您遇到的问题。但是，你可能会破坏一些东西。 –

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

到目前为止，我所知道的，这似乎是一个问题，使用Blueprint CSS框架。这就是说，其他两个注意事项：

我注释掉<％= stylesheet_link_tag “画面”，：媒体=> “屏幕” ％>从我application.html.erb布局文件的代码。
我没有安装'rubyracer'gem。我安装它，因为它在引用的答案的配置文件中。我不知道它做了什么。
无论我有链接，URL斜杠（“/”）现在都会再次显示。我的预感是，它只是一些CSS文件中的东西，我不得不深入并进行调试。但是，首先我有stylesheet_link_tag事情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。

希望这对别人有帮助！

另外，我在本地预编译所有东西（bundle exec rake assets：precompile）和heroku（heroku run bundle exec rake assets：预编译） – jflores

嗨，很高兴它的工作！如果此答案解决了您的问题，则应点击大号复选框将答案标记为“已接受”。这有助于人们知道您的问题已得到解决:)请参阅[此常见问题解答条目]（http://meta.stackexchange.com/a/5235/189918）。欢迎来到堆栈溢出！ – culix

谢谢你提醒我！这个解决方案实际上并不完美，因为我仍然有这些斜杠。但是，我最终弄清楚了，所以我发布了一个解决这两个问题（编译问题和URL /斜杠问题）的答案。 – jflores
