1.移除现有的Ruby
$gem sources --remove https://rubygems.org/
$gem sources -a https://ruby.taobao.org/
$gem sources -l
成功后提示：

$sudo gem install cocoapods
这时候提示：

ERROR: Error installing cocoapods:
activesupport requires Ruby version >= 2.2.2.
这个地方很坑，之前安装cocoapods一直是没有这个问题的，这里提示Ruby版本要大于或等于2.2.2
于是查看ruby版本
$ruby -v
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]
果然这里就要升级Ruby版本啦
查看目前的所有ruby版本：
$rvm list known
如果提示command not found 请先安装rvm
$curl -L get.rvm.io | bash -s stable
如果已安装会列出所有的ruby版本：

这里我们安装2.2.2:
$rvm install 2.2.2
终端运行结果：（如果直接成功请绕过homebrew的卸载安装）

然后再安装 CocoaPods
sudo gem install cocoapods
备注：苹果系统升级OSX10.11EICapitan后安装改为:
sudo gem install -n /usr/local/bin cocoapods
关于cocoapods的用法就不再多说了，有很多。这里是总结了本人安装cocoapods里遇到的坑以及解决办法，希望能有所帮助。
结果安装成功
