看起来像是OP编辑了原始邮件中的错误，因此以下答案不再相关。把它留在这里留给子孙后代。

已更新答案

根据Github中关于rbenv回购的几个问题的讨论，

• https://github.com/rbenv/ruby-build/issues/1480
• https://github.com/rbenv/ruby-build/issues/1489

听起来像是苹果更改了默认的CFLAGS作为Xcode12的一部分，这使得一些本地扩展安装变得混乱。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

原始答案

错误说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

所以我建议您先尝试手动安装这些扩展，然后重试Ruby安装。

使用BREW：

brew install readline
brew install zlib

ruby-build的GitHub上有一些问题可能也有帮助：
