问Nokogiri gem不工作

EN

我使用的是Rvm和ruby 2.1.5p273。

nokogiri安装者：gem install nokogiri

它的安装非常完美：

Successfully installed nokogiri-1.6.5
Parsing documentation for nokogiri-1.6.5
Done installing documentation for nokogiri after 3 seconds
1 gem installed

键入后：

gem list | grep nokogiri

我明白了：nokogiri (1.6.5)

这一切都在Mac Yosemite上。

require 'nokogiri'

显示：LoadError: cannot load such file -- nokogiri/nokogiri

我搜索了所有的SO和其他论坛，几个小时都没有解决方案。

gem env
