1.gem install cocoapods

ERROR:  While executing gem ... (Errno::EPERM)
Operation not permitted - /usr/bin/pod

用下面命名安装

sudo gem install -n /usr/local/bin cocoapods

2.更换更新数据源国内镜像,每天都更新code.net

pod repo remove master
pod repo add master https://git.coding.net/CocoaPods/Specs.git    
pod setup

3.常用更新安装命名,不进行本地库更新

更新

pod update --verbose --no-repo-update 

安装

pod install --verbose --no-repo-update

4 安装和卸载pod

sudo gem uninstall cocoapods  卸载
sudo gem install cocoapods    指定版本追加(-v 0.39) 安装
