我不明白为什么这里会提到旧版本的 ruby？
使用 XCode > pod install 失败，因为旧版本的 ruby 也被引用。

我尝试了 SO 中提出的不同解决方案，但无法解决此问题
- 卸载所有 gem 并重新安装
- 卸载 pod 并重新安装

Cocoapods install documentation 说“我们建议您使用默认的 ruby”，这是
/usr/bin/ruby中的那个。我不是 cocoapods 用户，所以我不知道这是否已连接到pods命令或者可以通过使用/usr/local/opt/ruby/bin/gem执行gem install cocoapods命令来覆盖。
