我一直在尝试安装Nokogiri，但最终我遇到了错误。
我有一个Jekyll网站，托管在Github上，当我克隆网站后尝试bundle install时，我在安装Nokogiri时会出现错误。
首先我尝试了这两个：
bundle config build.nokogiri --use-system-libraries
bundle install.
给了我以下错误：
Errno::EACCES: Permission denied - /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-15/2.0.0/nokogiri-1.6.8/gem_make.out
An error occurred while installing nokogiri (1.6.8), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.8'` succeeds before bundling.
在我第二次安装时尝试使用：
gem install nokogiri
导致我出现以下错误消息：

************************************************************************
IMPORTANT NOTICE:
Building Nokogiri with a packaged version of libxml2-2.9.4.
Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:
gem install nokogiri -- --use-system-libraries
[--with-xml2-config=/path/to/xml2-config]
[--with-xslt-config=/path/to/xslt-config]
If you are using Bundler, tell it to use the option:
bundle config build.nokogiri --use-system-libraries
bundle install
Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

使用rbenv和RVM升级Ruby并使用命令后问题得以解决：
bundle install --path vendor/bundle
