ruby in jekyll 06 May 2014
分享按钮在用github写博客的时候发现很多蛮有意思的东西，但这些东西都还需要自己慢慢的研究。这里主要对ruby的安装和本地jekyll的构建做一个简单的介绍，方便自己今后查阅。
##Ruby Install 可怜的mac用户，自从升级了Mac OS 10.9.2，我的ruby的bundler安装jekyll的依赖包就一直编译不过，花了点时间研究，发现是gcc的问题，没细致的去解决，实在是没时间。干脆就在Mac上安装了一个CentOS的虚拟机，在跑ruby，什么问题都没有，简单介绍一下安装过程和bundler的介绍。
###CentOS安装基础依赖包
kevinzhang:~ kevin# yum install gcc-c++ patch readline readline-devel zlib zlib-devel
kevinzhang:~ kevin# yum install libyaml-devel libffi-devel openssl-devel make
kevinzhang:~ kevin# yum install bzip2 autoconf automake libtool bison iconv-devel###安装RVM 安装最新稳定版本的RVM对Ruby进行包进行管理和安装。
kevinzhang:~ kevin# curl -L get.rvm.io | bash -s stable###设置RVM环境变量
kevinzhang:~ kevin# source /etc/profile.d/rvm.sh###安装Ruby
kevinzhang:~ kevin# rvm install 2.1.1###设置默认Ruby版本
kevinzhang:~ kevin# rvm use 2.1.1 default
Using /usr/local/rvm/gems/ruby-2.1.1
[root@dev ~]# rvm list
rvm rubies
=* ruby-2.1.1 [ x86_64 ]###检查Ruby版本是否正确
kevinzhang:~ kevin# ruby -v
ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-linux]##bundle 在Ruby中引入了bundle来管理Ruby项目的gem依赖，可以看到jekyll项目也是采用这样的方式组织项目的gem依赖。那么如何采用bundle来管理gitpage的gem包依赖。可以查看blog根目录下的Gemfile和Gemfile.lock文件，文件内容如下：
Gemfile
[root@dev topshare.github.com]# cat Gemfile

gem 'github-pages'Gemfile.lock

github-pages所有project的信赖包都在Gemfile中进行配置，不再像以往那样，通过require来查找。这里可以看到整个项目依赖github-pages，如果github-pages有新的更新，可以通过bundle去更新依赖。

Your bundle is updated!这样bundle会去检查 http://rubygems.org/ 上 gem的最新版本，如果本地旧的话，会去更新到最近版本。然后同步更新Gemfile.lock
Gemfile.lock 则用来记录本机目前所有依赖的 RubyGems 和其版本，所以强烈建议将该文件放入版本控制器，从而保证大家基于同一环境下工作。
如果你需要锁定某个开发环境采用bundle lock锁定，使用bundle unlock解锁，不过貌似最新的bundle已经去除了这两个功能。
These commands are obsolete and should no longer be used
o bundle lock(1)
o bundle unlock(1)
o bundle cache(1)如果缺少gem包，如果检查：
[root@dev topshare.github.com]# bundle check
The Gemfile's dependencies are satisfied##jekyll使用 新建一个jekyll：
[root@dev ~]# jekyll new abc启动一个jekyll本地服务：
[root@dev topshare.github.com]# bundle exec jekyll serve -w
