ActiveResource：：集合给NameError

Question

​

​

我试图在控制台上运行ActiveResource::Collection，但是它的名称出现了错误。请给我一个解决办法来解决这个问题。

 NameError: uninitialized constant ActiveResource::Collection
 from (irb):10
 from /var/lib/gems/2.1.0/gems/railties-3.2.17/lib/rails/commands/console.rb:47:in `start'
 from /var/lib/gems/2.1.0/gems/railties-3.2.17/lib/rails/commands/console.rb:8:in `start'
 from /var/lib/gems/2.1.0/gems/railties-3.2.17/lib/rails/commands.rb:41:in `<top (required)>'
 from script/rails:6:in `require'
 from script/rails:6:in `<main>'

更新

其他如ActiveResource::Base、ActiveResource::Format、ActiveResource::Connection等也在工作。

Answer 1

看起来你没有加入ActiveResource。将其添加到您的Gemfile中并运行bundle install。

# Gemfile
gem 'activeresource'

# Command line
bundle install

Answer 2

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。
