cocoapods安装教程

Mac OS 10.11, some cocoapods commands to change. If you have a pod setup or pod update problem, and it is difficult to solve, I suggest 10.11. Uninstall reinstall after installation of cocoapods has some different commands, the following summary:

1 。check the ruby environment, if necessary, please update as follows

$ sudo gem update --system

2 。uninstall cocoapods

$ sudo gem uninstall cocoapods

3 。reinstall cocoapods (Setup command has changed)

Before 10.11

$ sudo gem install cocoapods

After 10.11

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

4 

$ sudo chmod +rx /usr/local/bin

$ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

//taking CocoaPods Specs repository copy to your computer under directory ~/.cocoapods

5 。pod setup

    setup过程中如果出现  error: RPC failed; curl 56 LibreSSL SSL_read: SSL_ERROR_SYSCALL, errno 54错误，就执行 $ git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master 命令应该就可以了。 

版本回退：

1.查看版本号：git reflog

2.回退到指定版本：git reset --hard 指定版本号（例：git reset --hard 3628164）
