在文本，開發環境中使用ruby-debug19在AppCloud上部署錯誤

Question

在EY AppCloud中，即使您在開發環境中運行，它們也將運行捆綁程序-無需進行開發和測試。 我的Gemfile包含這個

group :test, :development do
  gem 'ruby-debug19', :require => 'ruby-debug'
end

當我部署時，出現此錯誤：

如果我注釋掉Gemfile中的gem'ruby-debug19'行，它將起作用。 但是無論如何都應該忽略這一點，因為如上所述，AppCloud忽略了測試，開發環境的寶石。 兩種情況下都可以在本地工作。 誰能想到這可能是什么原因？

Answer 1

我相信這是因為config/application.rb調用Bundler.require帶有一些組名，其中一個是Rails.env 。 命令行上的RAILS_ENV是development ，這意味着Bundler.require試圖加載development組並需要其中的內容，包括ruby-debug 。 由於已安裝了捆綁包，因此development小組無法使用。

也許最好用development的RAILS_ENV運行你的應用程序時本地，要么staging或production上AppCloud您的應用程序。

Answer 2

AppCloud默認情況下不安裝“開發”或“測試”組。 您需要在eydeploy.rb文件中進行配置。 您可以在http://docs.engineyard.com/bundler-tips-for-appcloud.html上找到有關安裝組的文檔。
