$ gem --version (查看gem版本)
1.移除现有Ruby默认源 $ gem sources --remove https://rubygems.org/
2.使用新的源 $ gem sources -a https://ruby.taobao.org/
3.验证新源是否替换成功 $gem sources -l
4.安装CocoaPods
(1) $sudo gem install cocoapods 备注：苹果系统升级 OS X EL Capitan 后改为 $sudo gem install -n /usr/local/bin cocoapods
(2) $pod setup
5.更新gem $sudo gem update --system
6. 新建工程，并在终端用 cd 文件拖到控制台 最后是 bogon:~ ibokan$ cd /Users/ibokan/Desktop/kk
