CocoaPods安装出现的新问题

• 之前曾发表过一篇关于CocoaPods安装的问题http://www.jianshu.com/p/9c209bcb475b
  如今发现出现了好多问题。
• 我查了一下，找到了解决办法，给大家分享一下
• Ruby版本更新不了
• 安装过程中出现如下提示
  ERROR: Error installing cocoa: activesupport requires Ruby version >= 2.2.2.
• 1.安装 RVM baby 版本管理器
  $ curl -L get.rvm.io | bash -s stable
  打印代码：
  In case of problems: https://rvm.io/help and https://twitter.com/rvm_io
• 2.测试
  $ source ~/.bashrc
$ source ~/.bash_profile
• 3.查看版本
  rvm -v
• 4.用RVM升级Ruby
  列出已知的ruby版本
  $ rvm list known
  安装ruby 2.2.2
  $ rvm install 2.2.2

Searching forbinary 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.

现在就可以查看版本了
$ ruby -v
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]
是不是很高兴、、
接下来就可以安装CocoPods喽、

补充下安装CocoPods出现的问题

• 添加完镜像后
• 出现[!] To setup the master specs repo, please run pod setup
• 我的解决办法，重新打开窗口
  git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master
• 完成以后·pod setup
• 多等一会（不要慌），应该就OK了。
