1.CocoaPods的安装，首先要安装好Ruby。
2.Ruby的安装
2.1在终端输入（要等一段时间）
curl-L https://get.rvm.io | bash -s stable
然后输入
source~/.rvm/scripts/rvm
输入（检查版本）
rvm-v
如何有返回
rvm1.29.3(latest)byMichalPapis,PiotrKuczynski,WayneE.Seguin[https://rvm.io]
说明安装RVM成功
输入（更新RVM）
rvmgetstable
3.安装Ruby
在终端输入 rvm list known ，列出所有可安装的版本

3.2 挑一个安装
终端输入 rvm install 2.4.0
如果报错：
则需要先在终端输入 ：rvm autolibs disable 再输入 rvm install 2.4.0 就没事了，没有报错就忽略这个。
安装成功

设置默认版本 rvm use 2.4.0 --default
到这里Ruby环境安装就结束了。
4.安装CocoaPods
本来是直接在终端敲入以下代码就可以，因为有墙，所以需要使用淘宝镜像。
sudogem install cocoapods
在终端输入
gem sources --removehttps://rubygems.org/
接着输入
gem sources -ahttps://ruby.taobao.org/
如果报错：
则换另一种方法：
在终端输入：$gem source -a http://rubygems.org/ to read
会跳出什么DO YOU Want.... 输入y。
然后 输入gem source -a http://rubygems.org/ to read
输入开机密码，就成功了。
