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

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：
-
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-]1.8.7[-head] # security released on head
[ruby-]1.9.1[-p431]

Ruby was built without documentation, to build it run: rvm docs generate-ri更新过程中可见顺带着将 gem 更新到了2.6.12

$ rvm list
$ rvm list
rvm rubies
* ruby-2.2.2 [ x86_64 ]
=> ruby-2.4.0 [ x86_64 ]
# => - current
# =* - current && default
# * - default发现rvm的默认版本还不是2.4.0
-
$ rvm --default use 2.4.0 改变默认版本为2.4.0
-
$ gem source -l 查看 ruby 源
若是
*** CURRENT SOURCES ***
https://ruby.org/则将其换为国内的源
gem sources --add https://ruby.taobao.org
gem sources --remove https://rubygems.org/国内两个可用源都可以：
https://ruby.taobao.org
https://gems.ruby-china.org -
更新gem看是否还有内容需要更新
$ sudo gem update -n /usr/local/bin —system -
卸载旧的cocoapods(如果有的话)
$ sudo gem uninstall cocoapods -
安装cocoapods
sudo gem install -n /usr/local/bin cocoapods完成：
