Rails控制檯 - Hpricot，Nokogiri在Rails控制檯中不可用？

Question

我一直沒有找到解決辦法如下：

安裝寶石後，如hpricot或nokogiri，我無法在rails控制檯中訪問這些。寶石出現在我的寶石列表中，並且似乎與我的其他寶石有相同的路徑。

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 

在控制檯，對於 「標準」 的寶石，他們能夠要求，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 script/rails:9:in `<main>' 

無論如何，我真的很感謝幫助我的新問題，一直在這一天的大部分時間裏掙扎。 :)

您是否將寶石添加到Gemfile中？當控制檯啓動時，它們將自動加載。
