尝试添加 devise_invitable gem。 :invitable 在我的设计模型（用户）中导致错误
Trying to add devise_invitable gem. :invitable in my devise model (User) is causing errors
我正在尝试安装 scambra/devise_invitable gem。手动和自动安装方式均无效。
我将 gem 添加到 Gemfile，运行ning 捆绑安装，然后尝试 运行 rails generate devise_invitable:install 或 rails g migration CreateDeviseInvitable 及其相应的代码，并在在这两种情况下，我都将堆栈跟踪放在要点中：https://gist.github.com/anonymous/c0b40c1970dd586ed8c8. If I keep the module in my Gemfile, I am unable to generate to continue the steps decribed in https://github.com/scambra/devise_invitable。我也无法再启动服务器，除非我删除 gem.
看起来像 a fix for this was merged into devise_invitable on December 31, 2015. Your version of devise_invitable (1.5.5) was released on December 17, 2015. If you're committed to your current versions of Devise and Rails, you might try pulling the gem from GitHub 而不是 RubyGems。
