静态网站生成器Jekyll 是一个简洁的、特别针对博客平台的 静态网站 生成器。它使用一个模板目录作为网站布局的基础框架，并在其上运行 Textile 、 Markdown 或 Liquid 标记语言的转换器，最终生成一个完整的静态Web站点，可以被放置在Apache或者你喜欢的其他任何Web服务器上。它同时也是 GitHub Pages 、一个由 GitHub 提供的用于托管项目主页或博客的服务，在后台所运行的引擎,本站基于Jekyll构建.
安装过程如下：
$ gem install jekyll
Fetching: liquid-2.5.5.gem (100%)
Successfully installed liquid-2.5.5
Fetching: fast-stemmer-1.0.2.gem (100%)
ERROR: Error installing jekyll:
The 'fast-stemmer' native gem requires installed build tools.
Please update your PATH to include build tools or download the DevKit
from 'http://rubyinstaller.org/downloads' and follow the instructions
at 'http://github.com/oneclick/rubyinstaller/wiki/Development-Kit'
报错了，提示我们下载安装"DevKit"，这里下载安装即可，然后又提示我们在http://github.com/oneclick/rubyinstaller/wiki/Development-Kit找答案。
安装了DevKit后切换到DevKit的安装目录：cd<devkit_install_dir>
执行 ruby dk.rb init 生成config.yml配置文件
最后 ruby dk.rb install 安装 DevKit 到你ruby中。对于64位操作系统来说，
可能会报错：‘Invalid configuration. Please fix ‘config.yml’ and rerun ‘ruby dk.rb install’`.
解决方案是将ruby目录的绝对路径写在config.yml中，如下：
# This configuration file contains the absolute path locations of all # installed Rubies to be enhanced to work with the DevKit. This config # file is generated by the 'ruby dk.rb init' step and may be modified # before running the 'ruby dk.rb install' step. To include any installed # Rubies that were not automagically discovered, simply add a line below # the triple hyphens with the absolute path to the Ruby root directory. # # Example: # # --- # - C:/ruby19trunk # - C:/ruby192dev # --- - C:\Ruby200-x64
注意规则：在---下，以 - 开头，然后空一格，然后是写ruby的绝对路径。
然后再试 ruby dk.rb install.如下提示：
$ ruby dk.rb install [INFO] Updating convenience notice gem override for 'C:/Ruby200-x64' [INFO] Installing 'C:/Ruby200-x64/lib/ruby/site_ruby/devkit.rb'
那么就说明安装成功了，然后就安装jekyll吧
$ gem install jekyll
