首先，我是关于Ruby的新手，正在遵循distilled.net/resources/web-scraping-with-ruby-and-nokogiri-for-beginners的简单教程。我有一个test.rb文件，其中包含以下内容：rubyrequire 'rubygems'require 'Nokogir'
首先,我是关于 Ruby的新手,我正在遵循 www.distilled.net/resources/web-scraping-with-ruby-and-nokogiri-for-beginners/的简单教程我有一个test.rb文件,其中包含以下内容：
require 'rubygems' require 'Nokogiri' require 'HTTParty' require 'Pry' require 'csv' # this is how we request the page we're going to scrape page = HTTParty.get('newyork.craigslist.org/search/pet?s=0') Pry.start(binding)
当我尝试运行ruby测试脚本时,我收到以下错误：
pjw@ubuntu:~/ruby/test$ruby test.rb /home/pjw/.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- HTTParty (LoadError) from /home/pjw/.rvm/rubies/ruby-2.3.0/lib/ruby/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require' from test.rb:1:in `<main>'
我已通过运行验证HTTParty正常工作：
newyork.craigslist.org/search/pet?s=0"
问题似乎是require语句.如果我混合订单或所需的宝石,第一个给出与上面相同的错误.我在网上搜索过,似乎找不到我错过的东西……
