Ruby on rails Rails（3.2.16）路由错误未初始化常量InheritedResources

我正在将Rails 2.3应用程序升级到3.2-这样做时，我以前依赖的

ResourceController

插件之一在Rails 3中不再可用（至少我发现它不是一个好端口）。因此，我不得不寻找其他选项，我尝试过的每一块宝石都会导致同样的错误：

路由错误未初始化常量[ResourceController | InheritedResources]

它们肯定在我的gemlock中，我已经在测试它们时重新启动了服务器。似乎gems没有安装，这样的错误就发生了

以下是我在

资源：项目中的路线：

                projects GET      /projects(.:format)                      projects#index
                     POST     /projects(.:format)                      projects#create
         new_project GET      /projects/new(.:format)                  projects#new
        edit_project GET      /projects/:id/edit(.:format)             projects#edit
             project GET      /projects/:id(.:format)                  projects#show
                     PUT      /projects/:id(.:format)                  projects#update
                     DELETE   /projects/:id(.:format)                  projects#destroy

这是控制器：

class ProjectsController < ResourceController::Base
#....
end

## OR

class ProjectsController < InheritedResources::Base
## ....
end

以下是对继承资源的回溯：

究竟为什么这些不可用？
您已将其添加到您的GEM文件中？您已经运行了bundle安装吗？您重新启动了服务器？我已经发布了上面的gemfile内容。是的-我已经完全重新启动了服务器。你能进入rails控制台并键入InheritedResources而不出错吗？如果发生错误，您能要求它并重试吗？不，我得到
NameError:uninitialized constant InheritedResources
Hmm！是的，我能`需要“inherited_resources=>true”，则InheritedResources可用。我需要在application.rb文件中使用此选项吗？？
[myself]:myapp(upgrade/rails-3.2)$ cat Gemfile | grep inherited
gem 'inherited_resources'

[myself]:myapp(upgrade/rails-3.2)$ cat Gemfile.lock | grep inherited
    inherited_resources (1.4.1)
  inherited_resources
