我认为销售商都没有发现。
尝试运行bundle命令将其安装在本地计算机上。

我不知道这是有益的，但我也得到了以下警告
弃用警告：你的Rails 2.3风格的插件，供应商/插件！在Rails 4.0中将会删除对这些插件的支持。将它们移出并将它们捆绑到Gemfile中，或者将它们作为lib/myplugin/*和config/initializers/myplugin.rb折叠到您的应用程序中。有关详情，请参阅发行说明：http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released。 （在.../appname/Rakefile中调用：7）
我在运行'bundle'命令时没有解决问题（运行bundle install） – 2014-10-20 05:51:56
，控制台说什么？ – 2014-10-20 08:25:18
您的套件已完成！ 使用'bundle show [gemname]'查看捆绑的gem的安装位置。 – 2014-10-20 10:46:55
