错误提示1
Error installing cocoapods: activesupport requires Ruby version >= 2.2.2.
解决方案 ：
1、安装 RVM baby 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
执行
$source ~/.bashrc
$source ~/.bash_profile
测试是否安装正常
$rvm -v
//________提示以下___________
rvm 1.27.0 (latest) by Wayne E. Seguin, Michal Papis[https://rvm.io/]
2、用RVM升级Ruby查看当前ruby版本
$ruby -v

安装ruby 2.2.2 执行
$rvm install 2.2.2
干货1：安装ruby遇到" Installing Homebrew - Brew Command Not Found"命令找不到解决方案：
Check XCode is installed or not.
$gcc --version
$ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
$brew doctor
$brew update.
完成后 执行
$ruby -v
//–––––打印输出–––––––
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]
6 继续安装 CocoaPods
$sudo gem install cocoa pods
//______安装成功提示如下______
Done installing documentation for nap, fourflusher, escape, colored, concurrent-ruby, thread_safe, tzinfo, i18n, activesupport, claide, xcodeproj, molinillo, cocoapods-try, netrc, cocoapods-trunk, cocoapods-stats, cocoapods-search, cocoapods-plugins, cocoapods-downloader, cocoapods-deintegrate, fuzzy_match, cocoapods-core, cocoapods after 21 seconds,23 gems installed
$pod setup
备注：苹果系统升级 OS X EL Capitan 后安装改为:
$sudo gem install -n /usr/local/bin cocoapods
$pod setup
干货2：CocoaPods无限卡在Setting up CocoaPods master repo解决方案：
对于初次使用CocoaPods的同学，即使你不使用pod setup命令，在你初次执行pod install命令时，系统也会自动执行pod setup。而由于网络不稳定的原因，不挂VPN是不可能成功执行pod setup的。(我大天朝的墙啊~~~~)
$ pod repo remove master
$ git clone https://github.com/CocoaPods/Specs.git ~/.cocoapods/repos/master
$ pod repo update
7 更新 gem
$sudo gem update --system
8 新建工程，并在终端用 cd 指令到文件夹内
$pod search 第三方
9 新建 Podfile 文件
$ touch Podfile
10 编辑 Podfile 文件，并写入要添加的第三方库(cocoapod1.0.1版本Podfile文件的内容格式要求发生了变化，必须指出指出所用第三方库的target)
platform:ios, '8.0'
#use_frameworks!个别需要用到它，比如reactiveCocoa
target 'XXXApp' do
pod 'AFNetworking', '~> 2.3.1'<-------第三方
end
11 导入第三方库
$pod install --no-repo-update

老是卡在这一步，请问大神是什么原因啊
$ ruby -v
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin16]
然后运行sudo gem install cocoa pods 提示
ERROR: While executing gem ... (Gem::Exception)

求解答
yum -y install openssl-devel
yum -y install openssl
进入ruby 源码目录下的ext/openssl 目录：
cd /usr/local/src/ruby-2.2.3/ext/openssl/
执行 ruby ./extconf.rb ：
[root@server openssl]# ruby extconf.rb
checking for t_open() in -lnsl... no
checking for socket() in -lsocket... no
checking for assert.h... yes
checking for openssl/ssl.h... yes
..........................................................................中间略..........................................................................
checking for EVP_CTRL_GCM_GET_TAG in openssl/evp.h... yes
creating extconf.h
creating Makefile
将ruby 源码目录下的include 目录软链接到 / 目录下：
[root@server openssl]# ln -s /usr/local/src/ruby-2.2.3/include /
编译安装：
make && make install
然后就好了！
再运行：
gem install redis
即可正常运行！！

Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.11/x86_64/ruby-2.2.2.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx.
