今天装jekyll，总是失败。各种报错

最后装了最新的ruby搞定

步骤：

　　首先安装rvm

• yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel
• curl -L get.rvm.io | bash -s stable
• source /etc/profile.d/rvm.sh

　　安装最新的ruby

• rvm install ruby-head时出错

Warning! Requested ruby installation which requires another ruby available - installing one first.


To proceed rvm requires a ruby-1.9|ruby-2 compatible ruby is installed.
We attempted to install ruby automatically but it failed.
Please install it manually (or a compatible alternative) to proceed.

• 于是 按要求，rvm install ruby-1.9

• rvm install ruby-2.1.1

•  gem install jekyll
• 结束，OK
