Ruby on rails 在文本、开发环境中使用ruby-debug19在AppCloud上部署错误

在EY AppCloud中，即使您在development env中运行，它们也会运行bundler，而无需进行开发和测试。我的文件包含这个

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

部署时会出现以下错误：

AppCloud中记录的部署失败

如果我在Gemfile中注释掉gem'ruby-debug19'行，它就会工作。但无论如何都应该忽略这一点，因为正如前面提到的，AppCloud忽略了测试、开发环境gems。在这两种情况下，它都在本地工作。任何人都能想到这可能是什么原因吗？

我相信这是因为

config/application.rb

调用了

Bundler.require

，其中一个是

Rails.env

。命令行上的

RAILS\u ENV

是

development

，这意味着

Bundler.require

正在尝试加载

development

组并需要其中的内容，包括

ruby debug

。由于捆绑包已安装在

开发

组中，因此它会中断

---

在本地运行应用程序时，最好使用

development

进行

RAILS\u ENV

，在AppCloud上为应用程序进行

staging

或

production

。

AppCloud默认情况下不安装“开发”或“测试”组。您需要在

eydeploy.rb

文件中配置它。您可以在上找到有关安装组的文档。

为什么EY要这样做？似乎在每一种情况下，你只在开发组中放置了一些东西，应用程序将无法启动（当在EY上处于开发模式时）b/c它不会安装应用程序所需的gems。rb然后尝试安装这些gems？此外，在运行“bundle安装——无开发测试”之后，我无法在本地复制此功能。这似乎很奇怪。谢谢为什么EY会做什么？我可以在本地复制它：。不过，它似乎只有在出现

：require=>'ruby-debug19'

时才会中断。这可能是bundler中的一个bug。
