今天安装cocopods失败了，终端上说ruby的版本太低了了需要更新到ruby2.2.2版本

看上面这个网站更新ruby到指定版本，然后就报错了下面是错误代码

错误代码

在stackoverflow上面找了好久终于找到类似的答案，可能就是网络的问题，因为下载ruby的时候要下载相关的包

Installing requirements for osx.
Updating system…..
Installing required packages: autoconf, automake, libtool, pkg-config, libyaml, readline, libksba, openssl…..

下载这些包可能要翻墙，没办法翻墙试了一下果然成功了
