Rails控制台 - Hpricot，Nokogiri在Rails控制台中不可用？

Question

我一直没有找到解决办法如下：

安装宝石后，如hpricot或nokogiri，我无法在rails控制台中访问这些。宝石出现在我的宝石列表中，并且似乎与我的其他宝石有相同的路径。

user@user-laptop:~$ which nokogiri 
/home/user/.rvm/gems/ruby-1.9.2-p0/bin/nokogiri 
user@user-laptop:~$ which rake 
/home/user/.rvm/gems/ruby-1.9.2-p0/bin/rake 

在控制台，对于 “标准” 的宝石，他们能够要求，例如：

ruby-1.9.2-p0 > require 'open-uri' 
=> ["OpenURI"] 

然而，需要引入nokogiri返回如下：

ruby-1.9.2-p0 > require 'nokogiri' 
LoadError: no such file to load -- nokogiri 
    from /home/user/.rvm/gems/ruby-1.9.2-p0/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in `require' 
    from /home/user/.rvm/gems/ruby-1.9.2-p0/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in `block in require'

    from (irb):10 
    from /home/user/.rvm/gems/ruby-1.9.2-p0/gems/railties-3.0.0/lib/rails/commands/console.rb:44:in `start'

    from script/rails:9:in `require' 
    from script/rails:9:in `<main>' 

无论如何，我真的很感谢帮助我的新问题，一直在这一天的大部分时间里挣扎。 :)

您是否将宝石添加到Gemfile中？当控制台启动时，它们将自动加载。
