解决方法 #

• 重新编译nio4r本地扩展：错误根源是预编译的.so文件和当前系统/Ruby环境不兼容，执行以下命令：

  # 卸载现有nio4r
  gem uninstall nio4r
  # 重新安装（自动编译适配当前环境的扩展）
  bundle install
  # 或直接重新 pristine 该gem
  gem pristine nio4r
  

• 校验RVM环境一致性：确保当前使用的Ruby版本与gem安装路径匹配：

  rvm use ruby-3.2.1
  gem env
  

  检查输出中的RUBY VERSION和INSTALLATION DIRECTORY是否对应。
• 安装Fedora编译依赖：确保有编译本地扩展的工具链：

  sudo dnf install gcc ruby-devel make
  

• 清理缓存：避免旧缓存干扰：

  bin/rails tmp:clear
  rm -rf ~/.rvm/gems/ruby-3.2.1/cache/nio4r-*.gem
