Question

Ruby 1.9.3 非常简单的代码和我无法处理的非常简单的问题：

gem list --local
nokogiri (1.5.5)

gem q --local
nokogiri (1.5.5)

但是一个ruby脚本（不是Rails）：

require 'nokogiri'
doc = Nokogiri.XML("some valid xml....")

给了我

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- nokogiri (LoadError)
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /home/alex/test.rb:3:in `<main>'
[Finished in 0.1s with exit code 1]

我知道没有必要使用require 'rubygems'，但即使我这样做，它也不起作用。

gem which nokogiri
/home/alex/.rvm/gems/ruby-1.9.3-p194/gems/nokogiri-1.5.5/lib/nokogiri.rb

Answer 1

这是因为Sublime Text构建系统错误。正确的是How to run ruby files in sublime-text-2

Answer 2

你需要将Nokogiri添加到Gemfile中（使用行'gem'nokogiri'）。

Ruby 1.9.3 - 由于某种原因无法加载此类文件
