在macOS M2上用rbenv安装Ruby 3.2.2：缺失psych和libyaml问题

出现的错误信息：

yaml.rb:3: warning: It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.
The Ruby yaml extension was not compiled.
ERROR: Ruby install aborted due to missing extensions

解决步骤：

• 安装libyaml依赖（需提前安装Homebrew）：

  brew install libyaml
  

• 设置环境变量，让rbenv编译Ruby时能找到libyaml：

  export RUBY_CONFIGURE_OPTS="--with-libyaml-dir=$(brew --prefix libyaml)"
  

• 重新执行Ruby安装命令：

  rbenv install 3.2.2
  

• 若需永久生效该环境变量，将配置写入shell配置文件（以zsh为例）：

  echo 'export RUBY_CONFIGURE_OPTS="--with-libyaml-dir=$(brew --prefix libyaml)"' >> ~/.zshrc
  source ~/.zshrc
