下定决心把本地预览安装好，花了2天时间终于搞定。主要还是靠网上的教程，一步一步慢慢试。
window7 X64系统
1、Ruby 安装
ruby下载地址：http://rubyinstaller.org/downloads/
2、安装DevKit
DevKit下载地址：http://rubyinstaller.org/downloads/
- 解压到一个文件夹下，如c:\devkit
- cmd进入该地址，即c:\devkit
- 输入ruby dk.rb init
- 输入ruby dk.rb install
- 检查是否安装成功：gem install rdiscount –platform=ruby
3、安装jekyll
gem install jekyll- 进入项目文件
- jekyll serve
安装gem install jekyll 过程中可能会报如下错误：
ERROR: Could not find a valid gem 'jekyll' (>= 0), here is why:
Unable to download data from https://ruby.taobao.org/ - SSL_connect re
turned=1 errno=0 state=SSLv3 read server certificate B: certificate verify faile
d (https://ruby.taobao.org/specs.4.8.gz)
解决方法：（更换配置源）
- gem sources -l 查看当前配置源
- gem sources –remove https://rubygems.org/
- gem sources -a http://gems.ruby-china.org
在运行过程中会出现错误，则需要安装相关依赖。比如:
Dependency Error: Yikes! It looks like you don’t have jekyll-paginate or one of its dependencies installed. In order to use Jekyll as currently configured, you’ll need to install this gem. The full error message from Ruby is: ‘cannot load such file – jekyll-paginate’ If you run into trouble, you can find helpful resources at Getting Help
jekyll 3.1.2 | Error: jekyll-paginate
解决办法： gem install jekyll-paginate
有时候可能会有版本冲突，解决办法是先删除老版本(gem uninstall ...)，再安装新版本
