Question

我创建了一个ruby gem，我已经在我的一个rails-api应用程序中使用了它。我最近在gem中添加了一个配置，所以我可以从我的rails-api app配置它，看起来像这样：

# In rails-api app /config/initializers/my_gem.rb
MyGem::MyNamespace.configure do |config|
   config.allow_custom_commands = true
end

然而，当我启动rails服务器时，我收到NoMethod错误：

/Users/me/dev/rails/api.abc/config/initializers/my_gem.rb:61:in `<top (required)>': undefined method `configure' for MyGem::MyNamespace:Module (NoMethodError)
        from /Users/me/dev/rails/api.mohojo-werks/vendor/bundle/gems/activesupport-5.0.5/lib/active_support/dependencies.rb:287:in `load'
        from /Users/me/dev/rails/api.mohojo-werks/vendor/bundle/gems/activesupport-5.0.5/lib/active_support/dependencies.rb:287:in `block in load'
        from /Users/me/dev/rails/api.mohojo-werks/vendor/bundle/gems/activesupport-5.0.5/lib/active_support/dependencies.rb:259:in `load_dependency' 
etc.

我所有的宝石测试都没有通过，所以我不知道自己做错了什么。这是我的配置文件：

# /my_gem/configuration.rb    
module MyGem
    module MyNamespace

        class Configuration
            attr_accessor :allow_custom_commands

            def initialize
            reset
            end

         public
            def reset
                @allow_custom_commands = false
            nil
            end
        end
    end
end


# /my_gem/configure.rb
module MyGem
    module MyNamespace
        class << self
            attr_writer :configuration
        end

        def self.configuration
            @configuration ||= Configuration.new
        end

        def self.configure
            yield(configuration)
        end
    end
end

我似乎错过了一些＆＃39;要求＆＃39;在下面的文件中。添加它们之后，一切似乎都运行正常，我的配置块在我的rails-api app /config/initializers/my_gem.rb中运行良好......

# my_gem.rb
require 'my_gem/configure'

# /my_gem/configure.rb
require_relative 'configuration'

如何让我现有的ruby gem配置可用于我的rails-api应用程序？
