我有一个使用comfortable mexican sofa（舒适）的分叉的应用程序。我想将mercury-rails安装到舒适的地方。这样做的原因是我可以修改舒适以使用汞。
我首先将引擎的宝石添加到舒适的gemspec中。
s.add_dependency 'mercury-rails'
跑bundle install
然后继续安装，运行指南：
rails generate mercury:install
这给了我一个错误：
[WARNING] Could not load generator "generators/mercury/install/install_generator". Error: uninitialized constant Mercury::Engine.

现在我认为这是因为我试图在引擎而不是应用程序上安装它。我认为引擎不是设计用的。 如果我尝试从应用程序中运行相同的命令，也会出现此错误。
注意当我将gem添加到标准rails应用程序时，这是有效的。
我的问题是：
是否有关于在发动机内安装发动机的标准/文件？
如果没有，我将如何做到这一点？
