错误二
Error installing pods:active support requires Ruby version >= 2.2.0
原因
当前的 ruby 版本太低, 需要升级ruby 版本
解决方法
安装rvm(Ruby版本管理器)
// 判断是否安装rvm
$ rvm -v
command not found: rvm （如果显示这个是未安装，显示的是版本号请跳过这一部分直接进入安装ruby）
// 安装rvm
$ curl -L get.rvm.io | bash -s stable
// 使刚添加的命令生效
source ~/.rvm/scripts/rvm
// 参考是否安装成功
$ rvm -v
rvm 1.29.4 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

/Library/Ruby/Site/2.0.0/rubygems.rb:250:in `find_spec_for_exe': can't find gem cocoapods (>= 0.a) (Gem::GemNotFoundException)
from /Library/Ruby/Site/2.0.0/rubygems.rb:278:in `activate_bin_path'
from /usr/local/bin/pod:22:in `<main>’
