調試Heroku部署（500錯誤）

過去幾個晚上我一直在將我的第一個rails應用程序部署到heroku，並且一直在努力弄清楚如何解決這個問題。調試Heroku部署（500錯誤）

我使用Michael Hartl的教程（http://ruby.railstutorial.org/chapters/beginning#sec-deploying）來確保我在Cedar Stack上設置了我的應用程序。

根據Heroku教程，我使用「瘦」作爲服務器。

我讀了一堆的職位，並使用預編譯我的資產：

的Heroku運行包的exec耙資產：預編譯捆綁高管耙資產：預編譯

我也遷移我的數據庫。

我的應用程序在我的本地主機上工作。

這裏是我的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

這裏是我的Heroku的日誌

以下是我最終如何解決問題的方法。感謝那些在別處提到我的人，以便我可以將它們放在一起。

首先，我將Blueprint移動到了供應商目錄。我不認爲這對解決方案至關重要，但它感覺更清潔。

編譯問題：

這個線程：blueprint css rails 3.1 help是真的很有幫助。我發現Martin和Gary的回覆（第2和第3）比選定的回覆更有幫助。

爲什麼我在編譯（個人）時遇到問題，部分原因是我對Blueprint文件進行了一些編輯，這意味着他們需要在部署之前再次編譯。

此主題：rails 3.1.0 ActionView::Template::Error (application.css isn't precompiled)在這方面很有幫助。基本上，在上傳到heroku之前，運行「Bundle exec rake assets：precompile」。上傳後我還運行「heroku run rake assets：precompile」。

我是怎麼擺脫URL的斜線在我的鏈接： 的網址是此代碼藍圖/ print.css的結果：

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

我解決了註釋掉的代碼問題。當然，在更改文件之後，您必須重新分配資源：再次預編譯。但是，這一切都工作！

這看起來像重要的部分：

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

好像this thread將解決您的問題。

，因爲它說：

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

感謝您的回覆！我昨晚看過那篇文章並試了一下。根據你的建議，我今天早上再試一次。仍然沒有工作。儘管如此，我還沒有嘗試過你在這裏提倡的運行時編譯方法，因爲我讀過的所有內容都表明這樣做會有相當大的性能損失。我錯了嗎？ – jflores

是的，有，但我找不到任何其他選項來解決您遇到的問題。但是，你可能會破壞一些東西。 –

我在這裏找到了答案：blueprint css rails 3.1 help

到目前爲止，我所知道的，這似乎是一個問題，使用Blueprint CSS框架。這就是說，其他兩個注意事項：

我註釋掉<％= stylesheet_link_tag 「畫面」，：媒體=> 「屏幕」％>從我application.html.erb佈局文件的代碼。
我沒有安裝'rubyracer'gem。我安裝它，因爲它在引用的答案的配置文件中。我不知道它做了什麼。
無論我有鏈接，URL斜槓（「/」）現在都會再次顯示。我的預感是，它只是一些CSS文件中的東西，我不得不深入並進行調試。但是，首先我有stylesheet_link_tag事情的全部原因是因爲我試圖擺脫那些討厭的斜線。最終，我決定部署更重要。

希望這對別人有幫助！

另外，我在本地預編譯所有東西（bundle exec rake assets：precompile）和heroku（heroku run bundle exec rake assets：預編譯） – jflores

嗨，很高興它的工作！如果此答案解決了您的問題，則應點擊大號複選框將答案標記爲「已接受」。這有助於人們知道您的問題已得到解決:)請參閱[此常見問題解答條目]（http://meta.stackexchange.com/a/5235/189918）。歡迎來到堆棧溢出！ – culix

謝謝你提醒我！這個解決方案實際上並不完美，因爲我仍然有這些斜槓。但是，我最終弄清楚了，所以我發佈了一個解決這兩個問題（編譯問題和URL /斜槓問題）的答案。 – jflores
