CocosPods版本升级

最近发现本机的CocoaPods版本较老，就动手升级了，升级CocoaPods的步骤和安装的时候差不多，具体参考如下步骤:

1.查看下当前的版本号，命令如下:

pod --version // 本机版本1.2.1

2.升级前查看当前安装的Ruby源地址：

gbogon:~ mars$ gem source -l
*** CURRENT SOURCES ***
https://ruby.taobao.org/

3.由于目前淘宝的源不能用了，故移除淘宝的Ruby源，添加一个新的源

// 移除旧的源 命令: "gem sources --remove"

• bogon:~ mars$ gem sources --remove https://ruby.taobao.org/
• https://ruby.taobao.org/ removed from sources

// 添加新的源 命令: "gem sources -a https://gems.ruby-china.org/"

bogon:~ mars$ gem source -a https://gems.ruby-china.org/
https://gems.ruby-china.org/ added to sources

4.查看新源是否安装成功

bogon:~ mars$ gem source -l

*** CURRENT SOURCES ***

https://gems.ruby-china.org/

5.开始安装，输入如下命令：

bogon:~ mars$ sudo gem install cocoapods

6.再次查看CocoaPods的版本，升级成功！

bogon:~ mars$ pod --version
1.3.1

升级顺利 ，没有出现问题 ，故未列出任何升级异常状况。
