Rails 4 + Devise + Heroku

Question

即時嘗試將我的應用程序部署到Heroku。 我正在使用Rails 4，最新設計（試用3.0.0.rc和回購）和紅寶石1.9.3（也試過2.0）。 我無法過去的初步推動，似乎像heroku沒有看到設計。本地assets:precompile任務運行沒有問題。 這裏是輸出：

Answer 1

試試這個

rails generate devise:install 

Answer 2

heroku labs:enable user-env-compile -a myapp

這是一個資產管道的事情，而不是Rails4或設計。

Answer 3

您沒有在您的Gemfile中安裝therubyracer的寶石。

Answer 4

我不認爲therubyracer寶石會有所幫助。我自己並沒有使用它，而且我沒有遇到這個特殊的問題。由於Heroku使用了大量內存，因此現在也不鼓勵使用該寶石。他們正在使用Node來編譯資產。 （https://devcenter.heroku.com/articles/rails-asset-pipeline）

您是否在推送您的應用程序之前在Heroku上創建了數據庫？在此主題的討論表明，這可能會解決問題：https://github.com/plataformatec/devise/issues/1339。我與之合作的講師還讓他的學生在第一次推送他們的應用程序之前創建數據庫。如果你需要它，命令是：

heroku addons:add heroku-postgresql. 

如果不工作，另一種選擇是設置：

config.assets.initialize_on_precompile = false 

的設計文檔說，這是必要的設計使用Rails 3.1在Heroku上。我知道你使用的是Rails 4，所以這可能無濟於事 - 但如果首先創建數據庫不起作用，似乎值得嘗試。

Answer 5

都沒有這個問題，但我設置了看起來像在enivronment（C9）這個 的Gemfile

group :development, :test do 
    gem 'sqlite3' 
    ... 

我運行這個 捆綁安裝--without生產 另一個應用我正在工作關於我導入Postgress以避免開發和生產環境之間的任何可能的錯誤
