OP 似乎编辑了原始消息中的错误，因此以下答案不再相关。留在这里留给子孙后代。
更新答案
基于 rbenv 存储库中 Github 个问题的讨论，
听起来 Apple 更改了默认 CFLAGS 作为 xcode 12 的一部分，这使得一些本机扩展安装变得混乱。听起来这些问题中提出的解决方案是
CFLAGS="-Wno-error=implicit-function-declaration" rbenv install 2.2.2
原回答
错误表明由于扩展问题而失败
The Ruby readline extension was not compiled.
The Ruby zlib extension was not compiled.
ERROR: Ruby install aborted due to missing extensions
所以我建议先尝试手动安装这些扩展，然后重试 ruby 安装。
搭配酿造：
brew install readline
brew install zlib
关于 ruby-build 的 github 的一些问题可能也有帮助：
