我还没能找到解决办法:
在安装了gems(如hpricot或nokogiri)之后,我无法在rails控制台中访问它们。宝石出现在我的宝石列表中,而且似乎与其他宝石的路径相同。
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
在控制台中,对于“标准”gem,它们是必需的,例如:
ruby-1.9.2-p0 > require 'open-uri'
=> ["OpenURI"]
但是,要求nokogiri返回以下内容:
ruby-1.9.2-p0 > require 'nokogiri'
LoadError: no such file to load -- nokogiri

不管怎样,我真的很感谢你对我的新问题的帮助,这一天大部分时间我都在苦苦挣扎。:)
