安装rbenv遇问题：执行brew install rbenv提示无可用公式

当执行brew install rbenv时出现以下错误：

Warning: No available formula with the name "rbenv".
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

可以按以下步骤解决：

• 更新Homebrew本地公式索引，确保数据为最新状态：
  brew update
• 确认已添加Homebrew核心仓库的tap：
  brew tap homebrew/core
• 运行Homebrew诊断工具，修复可能存在的配置异常：
  brew doctor
• 完成上述操作后，再次尝试安装rbenv：
  brew install rbenv
