使用asdf安装Ruby后执行gem update --system遇架构不兼容错误求助

我通过macOS 14 Sonoma的Ruby安装指南，使用asdf安装了Ruby，执行gem update --system命令后触发以下错误：

1. 确认当前Ruby运行架构 #

执行以下命令查看Ruby的平台信息：

ruby -e "puts RUBY_PLATFORM"

如果输出为x86_64-darwin23，说明当前终端在x86_64（Rosetta）模式下运行，但已安装的stringio是arm64架构编译的，导致不兼容。

2. 卸载不兼容的stringio版本 #

gem uninstall stringio

在提示中选择卸载3.1.0版本。

3. 重新编译安装适配当前架构的stringio #

gem install stringio --platform=ruby

--platform=ruby参数会强制从源码编译gem，自动适配当前系统的CPU架构。

4. 重新执行gem更新 #

gem update --system

5. 若问题仍存在，重新安装适配架构的Ruby #

# 卸载现有Ruby版本
asdf uninstall ruby 3.3.0
# 确保终端处于对应架构模式（arm64用原生终端，x86_64用Rosetta终端）
asdf install ruby 3.3.0
asdf global ruby 3.3.0
