Cocoapods

升级 OS X El Capitan 后,Time Machine 恢复下,随后因为遇到 octopress 无法更新博客问题,一番折腾 octopress 适配了 OS X El Capitan,然而事情总没有那么简单,又丢过来一个问题。
和往常一样使用 Cocoapods ,执行命令:
$ pod install#输出信息/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:296:in to_specs': Could not find 'cocoapods' (>= 0) among 59 total gem(s) (Gem::LoadError) from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:307:into_spec' from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_gem.rb:47:in gem' from /usr/local/bin/pod:22:in

查看 Ruby
版本:
$ ruby -vruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin14]

看来是升级 Ruby 2.2.3

导致的问题,更新下 Cocoapods 即可,更新步骤:
1、 更新 gem ,国内需切换 gem source

$ sudo gem update --system

切换 gem source

$ gem sources --add https://ruby.taobao.org/ --remove https://rubygems.org/$ gem sources -l*** CURRENT SOURCES***https://ruby.taobao.org

2、 安装 cocoapods

$ sudo gem install cocoapods$ pod setup

和安装过程是一样的,再次查看 pod
版本:
$ pod --version 1.2.1
