如何在IRB中要求ActiveRecord [英] How to require ActiveRecord In IRB

问题描述

我想在我的IRB会话中加载ActiveRecord gem，但以下操作无效：

I would like to load the ActiveRecord gem in my IRB session, but the following is not working:

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>'

这都不是：

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中的宝石路径：

This is my Gem path in irb:

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

这是我的活动记录宝石：

and here are my active record gems:

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宝石之一加载到我的IRB会话中？

How do I load one of those ActiveRecord gems into my IRB session?

我看过< a href = https://stackoverflow.com/questions/39694428/requiring-activerecord-on-irb-ruby-no-rails?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa>此帖子和此帖子但是我很酷

I have looked at this post and this post, but I could not source a solution from either the questions or the answers.

推荐答案

尝试 require（'active_record' ）

如果您查看gem Github存储库，则实际文件名为active_record.rb，因此上述代码应该可以使用。

If you take a look at the gem Github repo the actual file name is active_record.rb so the above code should work.

https://github.com。 com / rails / rails / tree / master / activerecord / lib
