Ruby ActiveResource:：集合提供名称时出错

我试图在控制台上运行ActiveResource:：Collection，但其命名错误。请给我一个解决这个问题的办法

 NameError: uninitialized constant ActiveResource::Collection

更新

其他如ActiveResource:：Base、ActiveResource:：Format、ActiveResource:：Connection正在工作。

看起来您没有添加

ActiveResource

。将其添加到您的

GEM文件中

，然后运行

捆绑安装

# Gemfile
gem 'activeresource'

# Command line
bundle install

我通过将activeresource gem版本更新为activeresource-4.0.0解决了这个问题。早些时候是activeresource-3.2.17

您是否重新启动了rails应用程序和rails控制台？activeresource:：Base正在工作
