【问题描述】：
当尝试通过 bundler/capistrano 安装 Nokogiri 时，我收到错误消息：
An error occurred while installing nokogiri (1.6.5), and Bundler cannot continue
深入挖掘我可以看到>> 需要libxml2 2.6.21或更高版本！
错误信息还写着Make sure that gem install nokogiri -v '1.6.5' succeeds before bundling.
好吧，正如你所看到的，这不是问题：
vagrant@vagrant:~$ gem install nokogiri -v '1.6.5'
Building native extensions. This could take a while...
Successfully installed nokogiri-1.6.5
1 gem installed
遗憾的是，即使通过了此测试，cap deploy 仍然会失败并出现相同的错误。
An error occurred while installing nokogiri (1.6.5), and Bundler cannot continue
我已经确保我的 virtualbox 上安装了最新版本的 libxml2。我什至删除了我的项目目录，并重新启动了服务器：
$ vagrant ssh
$ sudo apt-get update
$ sudo apt-get upgrade libxml2
$ sudo rm -rf /var/www/rails-devise-capistrano/
$ sudo reboot
我也尝试将其添加到 deploy.rb
set :bundle_env_variables, { nokogiri_use_system_libraries: 1 }
这是捆绑器错误

Building nokogiri using system libraries.
libxml2 version 2.6.21 or later is required!
