Error: Failed to upgrade Homebrew Portable Ruby!

这个报错是 Homebrew 在安装依赖（portable-ruby）时校验和不一致 导致的，常见于镜像源下载的文件损坏或者缓存文件过期。解决办法很简单：

✅ 解决步骤

删除损坏的缓存文件

rm -f /Users/song/Library/Caches/Homebrew/portable-ruby-3.3.8.arm64_big_sur.bottle.tar.gz
更新 Homebrew

brew update --force --quiet
brew upgrade
重新安装 wget

brew install wget

🔄 如果你一直遇到校验错误（因为用的是 USTC 镜像）

可以先切换回官方源再试：

复制代码

git -C "$(brew --repo)" remote set-url origin https://github.com/Homebrew/brew.git
git -C "$(brew --repo homebrew/core)" remote set-url origin https://github.com/Homebrew/homebrew-core.git
git -C "$(brew --repo homebrew/cask)" remote set-url origin https://github.com/Homebrew/homebrew-cask.git
brew update

然后再执行：

复制代码

brew install wget

就可以成功了：
