前言：
最近用回cocoapods，猛然发现一年前装的cocoapods已经出现了问题，pod install指令后并不能自动生成workspace，控制台输出为;
$ pod install
Analyzing dependencies
Downloading dependencies
Installing AFNetworking (3.1.0)
Installing SVProgressHUD (2.1.2)
Generating Pods project
Abort trap: 6
卸载cocoapods后重新安装会出现如下错误：
ERROR: While executing gem ... (OpenSSL::SSL::SSLError)
hostname "gems.ruby-china.org" does not match the server certificate
经过多方探索，基本猜到了问题：ruby版本太低了，我用的是2.2.2，是当时使用cocoapods的最低门槛，不知为何现在不行了。
既然定位了问题，我就索性重新安装了一遍，顺便记录一下安装步骤
安装环境：macOS 10.12.6
步骤：
- 若未安装rvm，则先安装rvm:
打开终端:$ curl -L https://get.rvm.io | bash -s stable
然后，载入 RVM 环境 $ source ~/.rvm/scripts/rvm
检查是否安装成功: $ rvm -v
若输入上面口令后显示:
rvm 1.27.0 (latest) by Wayne E. Seguin<wayneeseguin@gmail.com>,Michal Papis <mpapis@gmail.com> [https://rvm.io/]
表明安装成功
- 正式开始：
用
$ ruby -v查看当前 ruby 的版本用
$ rvm list known查看ruby所有的版本，我当时只能看到2.3，说明rvm不是最新的（rvm是一个便捷的多版本ruby环境的管理和切换工具）-
更新 rvm ：
$ rvm get stable(若能看到版本2.4则不用执行此操作)执行完再用
$ rvm list known查看：# MRI Rubies [ruby-]1.8.6[-p420] [ruby-]1.8.7[-head] # security released on head [ruby-]1.9.1[-p431] [ruby-]1.9.2[-p330] [ruby-]1.9.3[-p551] [ruby-]2.0.0[-p648] [ruby-]2.1[.10] [ruby-]2.2[.6] [ruby-]2.3[.3] [ruby-]2.4[.0] ruby-head -
