新电脑，安装cocoapods的时候报错，报错截图如下：

安装失败好久了，一直不是必须要安装pod，所以没有在意没去解决，今天实在要安装pod复现个问题，终于动手搜了下这个报错，试了下这个博客的解决方式，搞定。
报错原因猜测是ruby的版本和最新的pod版本兼容性有问题, 所以必须先升级ruby。
解决步骤：
-
安装 rvm
curl -L https://get.rvm.io | bash -s stable
安装成功会出现下图提示：
安装rvn成功.png
如果失败, 出现了这样的错误(报错内容 curl: (7) Failed to connect to raw.githubusercontent.com port 443: Operation timed out)，需要执行下列指令：
sudo gem install redis
然后继续执行rvm的安装命令：
curl -L https://get.rvm.io | bash -s stable
如果还是报 443 错误, 那就等一会再执行, 多次重试总会成功的。 安装 ruby 2.6
rvm install ruby-2.6
运行后：
