记录性质的文章。
1>. 升级gem
sudo gem update --system
2>. 移除现有 Ruby 默认源
gem sources --remove https://rubygems.org/
3>. 使用淘宝镜像源
gem sources -a https://ruby.taobao.org/
如果出现
Error fetching https://ruby.taobao.org/:
bad response Not Found 404 (https://gems.ruby-china.org/specs.4.8.gz)
则替换为gem sources -a https://gems.ruby-china.com/,一切出现404问题，都可以访问https://gems.ruby-china.org解决

4>. 验证当前镜像源
gem sources -l
5>. 安装cocoapods
系统升级 OS X EL Capitan 前：sudo gem install cocoapods
系统升级 OS X EL Capitan 后：sudo gem install -n /usr/local/bin
cocoapods（使用这个！）
6>. 如果步骤5成功则执行pod setup，成功后执行pod -version 检查版本
如果失败，比如：Error installing cocoapods: activesupport requires Ruby version >= 2.2.2. 则说明当前的ruby版本低于2.2.2，然后进行第7.
7>. 安装 RVM （ruby 版本管理器）
curl -L get.rvm.io | bash -s stable
//________等安装完成 出现下面这行提示以下___________
In case of problems: https://rvm.io/helpandhttps://twitter.com/rvm_io
8>. 执行
$source ~/.bashrc
$source ~/.bash_profile
9>. 检查rvm版本，看是否安装成功
rvm -v
//________提示以下___________
rvm 1.27.0 (latest) by Wayne E. Seguin, Michal Papis[https://rvm.io/]
10>. 使用rvm查看管理的所有ruby版本
rvm list known
//________提示以下___________
MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-head] # security released on head
[ruby-]1.9.1[-p431]

[ruby-]2.2[.4]
[ruby-]2.3[.0]
[ruby-]2.2-headruby-head
...# for forks use: rvm install ruby-head---url https://github.com/github/ruby.git --branch 2.2
...# JRuby
11>. 升级ruby
rvm install 2.2.2
12>. 安装homebrew
情形1:
//________提示以下___________
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.11/x86_64/ruby-2.3.0.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx.
About to install Homebrew, press `Enter` for default installation in `/usr/local`,
type new path if you wish custom Homebrew installation (the path needs to be writable for user)
如果出现以上信息可以直接回车，会安装homebrew相关的管理工具。
情形2:
//________提示以下___________

如果出现以上信息可以执行命令：ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
附homebrew官网：http://brew.sh/index_zh-cn.html
13>. 等12步homebrew安装完后再执行
rvm install ruby-2.3.0
//________成功提示___________

There has been an error fetching the ruby interpreter. Halting the installation.
解决办法：版本号只保留2位，改为命令rvm install 2.3即可
14>. 检查ruby版本
ruby -v
//________成功提示___________

ERROR: While executing gem ... (TypeError)

16>. 上边出错后更新gem
gem update --system
//________成功提示___________
RubyGems system software updated
17>. 再执行
sudo gem install -n /usr/local/bin cocoa pods
18>. 执行
pod setup
19>. 如果出现下面问题：
Setting up CocoaPods master repo
[!] /usr/local/bin/Git clone https://github.com/CocoaPods/Specs.git master
Cloning into 'master'...
error: RPC failed; curl 56 SSLRead() return error -36
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
依次执行：
sudo gem uninstall cocoa pods
pod repo remove master
sudo gem install -n /usr/local/bin cocoa pods
pod setup
20>. 如果第19步没有问题，表示安装OK，会看到如下信息
CocoaPods 1.2.0.beta.1 is available.
To update use: `sudo gem install cocoapods --pre`
[!] This is a test version we'd love you to try.
For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.2.0.beta.1
Setup completed
21>. 再检查版本
pod --version
出现：1.1.1
到此安装步骤全部完成！！！以上是我的安装步骤，也可以参照：http://blog.csdn.net/sharktoping/article/details/52311460
如果看不到最新版本，请使用 pod repo update 命令更新一下本地pod仓库
pod另一现象和解决办法
现象：[!] Unable to find a pod with name, author, summary, or description matching `YYkit`
解决办法： rm ~/Library/Caches/CocoaPods/search_index.json
