ERROR: Error installing cocoapods:

在网络上查询了以后 说是ruby 版本问题太低了就去尝试更新最新的的ruby，但是在电脑上安装最新的ruby 2.3.0 的时候安装不上遇到以下问题

有两个错误，在这里我要提醒各位不要去找这个错误的原因，因为我在这个坑里爬了很久都没爬出来我一直在找这个ruby无法更新的问题最后在StackFlower 上看见作者说是一个bug 没法找到长时间维护此项目的coder所以没有解决这个问题，所以这个问题我个人认为是还没法解决的。我在stackflower 上找到今天凌晨3点都没有找到这个问题的解决方案。
之后我转换思路，从解决 activesupport requires Ruby version >= 2.2.2.' 这个问题入手 我把Xcode 卸载了 重新装了一遍 在stack flower 找到的这句神奇的代码
sudo gem install activesupport -v 4.2.6
就没有问题了 我 没有更新 ruby 还是用的 2.0.0 系统的
之后运行 sudo gem install cocoa pods
瞬间让你G点的时刻就来了

大家遇见这个问题以后 千万不要去踩到 ruby 的版本更新的 问题里面去 因为这个问题解决不了 还浪费时间。
不行的话就卸载Xcode 然后按照 以上方法重新再来一次
