ruby-on-rails - 调试一个 rails gem，但 pry 并没有在断点处停止

Question

我想追踪做event_calendar什么，

所以我添加了 gem 然后捆绑安装，我发现它的安装位置在~/.rvm/gems/ruby-1.9.3-p448/gems/event-calendar-2.3.3/generators/event_calendar

所以我添加require 'pry'并嵌入到binding.pry我要调试的行中，

但是，当我运行rails g event_calendar

我以为它会调用event_calendar_generator.rb in~/.rvm/gems/ruby-1.9.3-p448/gems/event-calendar-2.3.3/generators/event_calendar

然而，它并没有在我预期的线路上被阻止。

 1 require 'pry'
  2 require File.expand_path(File.dirname(__FILE__) + "/lib/insert_routes.rb")
  3 binding.pry
  4 class EventCalendarGenerator < Rails::Generator::Base
  5   default_options :static_only => false,
  6                   :use_jquery =>  false,
  7                   :use_all_day => false
  8
  9   attr_reader :class_name, :view_name
 10
 11   def initialize(args, runtime_options = {})
 12     super
 13     binding.pry
 14     usage if args.length > 0 and args.length < 2
 15     @class_name = (args.shift || "event").underscore
 16     @view_name = (args.shift || "calendar").underscore
 17   end
