运行一些代码 CLI 风格，我注意到..
/Users/fizzy/.rvm/gems/ruby-1.9.3-p194/gems/shopify_api-3.0.1/lib/shopify_api/json_format.rb:3: warning: method redefined; discarding old encode
/Users/fizzy/.rvm/gems/ruby-1.9.3-p194/gems/activeresource-3.2.8/lib/active_resource/base.rb:1214: warning: previous definition of encode was here
/Users/fizzy/.rvm/gems/ruby-1.9.3-p194/gems/shopify_api-3.0.1/lib/shopify_api/json_format.rb:13: warning: method redefined; discarding old decode
/Users/fizzy/.rvm/gems/ruby-1.9.3-p194/gems/activeresource-3.2.8/lib/active_resource/formats/json_format.rb:20: warning: previous definition of decode was here
还有更多......是否有补丁来解决警告？
