要求“open-url”执行Nokogiri测试器时加载错误 [英] Require "open-url" load error when executing Nokogiri tester

问题描述

我试图按照RailsCast来使用Nokogiri。

I am trying to follow the RailsCast to use Nokogiri.

测试脚本文件中只有几行非常基本的代码：

Just a few very basic lines in my testing script file:

require 'rubygems'
require 'nokogiri'
require 'open-url'

url = "http://www.walmart.com/search/search-ng.do?search_constraint=0&ic=48_0&search_query=Batman&Find.x=0&Find.y=0&Find=Find"
doc = Nokogiri::HTML(open(url))
puts doc.at_css("title").text

但是当我执行它的时候，错误：

But when I execute it, I run into an error:

/usr/local/rvm/rubies/ruby-1.9.3-p392/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- open-url (LoadError)
    from /usr/local/rvm/rubies/ruby-1.9.3-p392/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:54:in `require'
    from nokogiri.test.rb:3:in `<main>'

我按照以下指示安装了开放网址gem： https://github.com/openurl/openurl
如何解决错误信息？

I did install open url gem following this instruction:https://github.com/openurl/openurl How do I fix the error message?

推荐答案

只是一个错字。使用 open-uri （不是 open-url ）。

Just a typo. Use open-uri (not open-url).
