升级MacOS Monterey后执行rails new命令报错，gem pristine无效如何解决

每次使用rails new命令创建Rails应用时都会触发报错，项目文件虽能正常生成，但报错始终无法彻底消除，故障首次出现于升级MacOS Monterey系统后。

已尝试以下操作均无效果：

• 更新Ruby版本
• 重新安装Rails
• 对全量gem执行pristine操作
• 用chruby安装Ruby后重新部署Rails环境

修复gem扩展未构建报错 #

该问题是系统升级后旧gem编译依赖的工具链发生变化，且全局rails命令调用了系统自带Ruby版本的依赖导致：

1. 执行ruby -v确认当前shell激活的是你自行安装的Ruby版本，而非系统自带的2.6.x版本
2. 执行which rails确认输出路径对应你安装的Ruby版本bin目录，若输出为/usr/local/bin/rails则执行sudo rm /usr/local/bin/rails清理全局旧执行文件
3. 在当前激活的Ruby环境下重新安装Rails：gem install rails
4. 重新编译对应版本的扩展gem：gem pristine racc --version 1.6.0 nio4r --version 2.5.8 websocket-driver --version 0.7.5

修复OpenSSL加密报错 #

该问题是Monterey系统自带OpenSSL版本与Ruby编译依赖的OpenSSL版本不兼容导致：

1. 用Homebrew安装兼容的OpenSSL 1.1版本：brew install openssl@1.1
2. 重新编译安装对应版本的Ruby，编译时指定OpenSSL路径（以Ruby 2.7.2为例）：

RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.1)" ruby-install ruby 2.7.2

3. 重新安装Rails及所有依赖gem后，再次执行rails new测试即可
