Heroku部署沒有格式？

讓我首先說我對heroku/ruby/rails很新。我正在通過Michael Hartl的Ruby on Rails教程，當我使用'rails s'在本地服務器上部署應用程序時，一切都顯示正常。但是，當我將我的應用程序推送到heroku並使用'heroku open'進行部署時，該應用似乎跳過了所有資產。我確認了資產管道已啓用，但仍然無法讓我的應用程序以任何格式部署到heroku上。Heroku部署沒有格式？

我一直在看heroku日誌，但似乎唯一的錯誤是一個致命的SignalException，但我不知道這是指什麼。此外，如果有人能夠解釋棄用警告是否嚴重，我會非常感激。

你可能會錯過在5.4步驟？

require File.expand_path('../boot', __FILE__) 
. 
. 
. 
module SampleApp 
    class Application < Rails::Application 

    config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif) 
end 
end

不知道你遵循的流程，但heroku open不是部署應用程序，這是隻有在瀏覽器中打開yourapp.herokuapp.com。

部署在Heroku上的應用程序，你必須：

創建應用程序：heroku create
使用Git，把你的代碼的Heroku：git push heroku master（Heroku的是遠程回購，使用的名稱git remote -v以確保你有heroku）。這將您的應用部署到heroku，捆綁安裝，創建數據庫和預編譯您的資產。
運行：heroku run rake db:migrate（你應該在你的Gemfile中使用MySQL或Postgres，sqlite會引發錯誤）。
最後heroku open。

看起來你忘步驟3

希望這有助於！
