在文本，开发环境中使用ruby-debug19在AppCloud上部署错误

Question

在EY AppCloud中，即使您在开发环境中运行，它们也将运行捆绑程序-无需进行开发和测试。 我的Gemfile包含这个

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

当我部署时，出现此错误：

如果我注释掉Gemfile中的gem'ruby-debug19'行，它将起作用。 但是无论如何都应该忽略这一点，因为如上所述，AppCloud忽略了测试，开发环境的宝石。 两种情况下都可以在本地工作。 谁能想到这可能是什么原因？

Answer 1

我相信这是因为config/application.rb调用Bundler.require带有一些组名，其中一个是Rails.env 。 命令行上的RAILS_ENV是development ，这意味着Bundler.require试图加载development组并需要其中的内容，包括ruby-debug 。 由于已安装了捆绑包，因此development小组无法使用。

也许最好用development的RAILS_ENV运行你的应用程序时本地，要么staging或production上AppCloud您的应用程序。

Answer 2

AppCloud默认情况下不安装“开发”或“测试”组。 您需要在eydeploy.rb文件中进行配置。 您可以在http://docs.engineyard.com/bundler-tips-for-appcloud.html上找到有关安装组的文档。
