如何修复Ruby与CocoaPods的架构不兼容LoadError问题？

执行任何操作都会输出以下错误日志：

新建项目能正常部署到iOS模拟器，但所有旧项目都出现这个问题，以下是解决步骤：

解决步骤 #

1. 卸载冲突的date gem #

额外安装的date-3.2.2是x86_64架构，和你的arm64e芯片不兼容，直接卸载：

sudo gem uninstall date -v 3.2.2

系统自带的date库已经适配arm架构，无需额外安装第三方版本。

2. 重新安装适配arm架构的CocoaPods #

先清理现有CocoaPods：

brew uninstall cocoapods
sudo gem uninstall cocoapods

然后用Homebrew重新安装适配arm的版本：

brew install cocoapods

如果还是有问题，推荐用Ruby版本管理器安装arm版Ruby后再装CocoaPods：

# 安装rbenv
brew install rbenv
# 安装适配arm的Ruby版本（比如3.2.2）
rbenv install 3.2.2
# 设置全局Ruby版本
rbenv global 3.2.2
# 安装CocoaPods
gem install cocoapods

3. 清理旧项目的Pod缓存 #

进入旧项目目录，执行以下命令重置Pod依赖：

pod deintegrate
rm -rf Podfile.lock
rm -rf ~/Library/Caches/CocoaPods
rm -rf ~/.cocoapods
pod install
