这个让我疯了.我可以通过irb加载一个gem:

steve@server:/var/www/listings$ irb
irb(main):001:0> Gem.path
=> ["/home/steve/.gem/ruby/1.9.1", "/usr/local/ruby/lib/ruby/gems/1.9.1"]
irb(main):002:0> require 'nokogiri'
=> true

但我无法通过rails控制台加载它:

irb(main):001:0> Gem.path
=> ["/home/steve/.gem/ruby/1.9.1", "/usr/local/ruby/lib/ruby/gems/1.9.1"]
irb(main):002:0> require 'nokogiri'
=> false

宝石(nokogiri)已安装

steve@server:/var/www/listings$ gem which nokogiri
/usr/local/ruby/lib/ruby/gems/1.9.1/gems/nokogiri-1.4.3.1/lib/nokogiri.rb

捆绑同意

steve@server:/var/www/listings$ bundle show nokogiri
/usr/local/ruby/lib/ruby/gems/1.9.1/gems/nokogiri-1.4.3.1

但是,当然,rake spec失败了

/usr/local/ruby/lib/ruby/gems/1.9.1/gems/activesupport-3.0.1/lib/active_support/dependencies.rb:304:in `rescue in depend_on': No such file to load -- Nokogiri (LoadError)

如何加载ActiveRecordIRB会话？

我有以下内容

# config/app.rb
require 'active_record'

ActiveRecord::Base.establish_connection(
  adapter:  'sqlite3',
  database: 'db/mydb.sqlite3'
)

但是当我启动IRB并尝试加载它时

irb#1(main):001:0> require config/application.rb

我明白了

NameError: undefined local variable or method `config' for main:Object
Did you mean?  conf

我希望能够与IRB的ActiveRecord对象进行交互.我不使用Rails但只使用ActiveRecord.

谢谢
