AI-generated summary

The article discusses issues encountered while trying to install HomeBrew on a Mac for compiling linphone. The author created a new user account and tried to install dependencies but encountered errors related to permission denied. They uninstalled HomeBrew from the old user account and tried to reinstall it on the new account but still faced permission denied errors. The solution involved clearing the git cache and removing Cellar.

自己的 MAC 工作机器上为了编译 linphone 创建了一个新用户，安装依赖包时提示 brew 未找到，重新安装 brew 时提示各种 Permission denied。干脆到旧用户账户下把 brew 卸载。然后到新用户下重新安装。

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

新用户下还是提示 Permission denied。继续安装不成功。再卸载出现以下情况

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Failed to locate Homebrew!

解决办法

#清理 git 缓存
rm -rf /usr/local/.git
#彻底清理 Cellar，尽量不要使用
#rm -rf /usr/local/Cellar
