緣由：

更新完xcode，然後要更新第三方套件時，假如遇到管理專案套件的cocoapods版本太舊的時候，就需要更新cocoapods，過去我是用Ruby gem安裝cocoapods，當然更新cocoapods也是可行的，每台Mac都有內建安裝好的Ruby，可以看看版本是不是新的，假如都需要更新，可以參考以下的更新順序：

查看Ruby → 查看rvm → 查看rvm可安裝版本 → 安裝Ruby最新版 → 檢查新Ruby版本 → 更新gem版本 → 使用gem安裝cocoapods → 可更新xcode專案第三方套件

實作：

打開Mac終端機，依序輸入以下指令，即可以更新ruby與cocoapods

HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
But that may break your application.
If you are upgrading your Rails application from an older version of Rails:
Please check your Rails app for ‘config.i18n.fallbacks = true’.
If you’re using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be
‘config.i18n.fallbacks = [I18n.default_locale]’.
If not, fallbacks will be broken in your app by I18n 1.1.x.
If you are starting a NEW Rails application, you can ignore this notice.
