ruby - 如何在 IRB 中要求 ActiveRecord

Question

我想在我的 IRB 会话中加载 ActiveRecord gem，但以下操作不起作用：

require 'activerecord'
2.4.1 :004 > require 'activerecord'
LoadError: cannot load such file -- activerecord
    from /Users/robskrob/.rvm/rubies/ruby-2.4.1/lib/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require'
    from /Users/robskrob/.rvm/rubies/ruby-2.4.1/lib/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require'
    from (irb):4
    from /Users/robskrob/.rvm/rubies/ruby-2.4.1/bin/irb:11:in `<main>'

这也不是：

2.4.1 :018 > require 'activerecord-5.1.2'
LoadError: cannot load such file -- activerecord-5.1.2
    from /Users/robskrob/.rvm/rubies/ruby-2.4.1/lib/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:120:in `require'
    from /Users/robskrob/.rvm/rubies/ruby-2.4.1/lib/ruby/site_ruby/2.4.0/rubygems/core_ext/kernel_require.rb:120:in `require'
    from (irb):18
    from /Users/robskrob/.rvm/rubies/ruby-2.4.1/bin/irb:11:in `<main>'

这是我在 irb 中的 Gem 路径：

        2.4.1 :012 > Gem.path
     => [
          "/Users/robskrob/.rvm/gems/ruby-2.4.1", 
          "/Users/robskrob/.rvm/gems/ruby-2.4.1@global
        ]

这是我的活跃记录宝石：

ls /Users/robskrob/.rvm/gems/ruby-2.4.1/gems/activere
activerecord-4.2.10/   activerecord-5.1.2/    activerecord-5.1.4/    activerecord-5.1.6/
activerecord-5.0.0.1/  activerecord-5.1.3/    activerecord-5.1.5/    activeresource-5.0.0/

如何将这些 ActiveRecord gem 之一加载到我的 IRB 会话中？

我看过这篇文章和这篇文章，但我无法从问题或答案中找到解决方案。

尝试require('active_record')

如果您查看 gem Github repo，实际文件名是 active_record.rb 所以上面的代码应该可以工作。
