我无法在 MacOS Apple Silicon 上卸载brew

Question

就像这里提到的https://docs.brew.sh/FAQ#how-do-i-uninstall-homebrew我输入了
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"但它似乎不起作用......

当我输入后which brew它返回/usr/local/bin/brew

当我再次输入时/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

它显示：

/bin/bash: 第 236 行: /opt/homebrew/bin/brew: 没有这样的文件或目录 无法找到 Homebrew！

所以我不知道该怎么做才能卸载brew。

我的最终目标是当我尝试安装brew包时不出现此错误：

错误：无法在 Intel 默认前缀 (/usr/local) 的 ARM 处理器上安装 Homebrew！
请使用https://docs.brew.sh/Installation中的“替代安装”之一在 /opt/homebrew 中创建新安装您可以使用以下命令迁移以前安装的公式列表：brew bundle dump

我现在拥有一台搭载 Apple Silicon 的 Mac，但我曾经拥有一台英特尔 Mac。

编辑1：我快速浏览了uninstall.sh这里的脚本https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh

看来我的问题是由我的操作系统安装引起的，因为我是通过基于 Intel 的 MacOS 时间机器备份完成的。问题是uninstall.sh脚本被编程为根据当前操作系统卸载自制程序。所以这个脚本只能卸载我需要的ARM自制程序，而无法卸载我试图摆脱的Intel自制程序......

也许我应该尝试更改检测我有 ARM CPU 的代码行，使脚本认为我有基于 Intel 的 Mac，但我不知道它是否会给我的计算机带来混乱......

我很惊讶关于这个问题的答案并不多，因为我不认为我是唯一一个使用 Time Machine 从基于 Intel 的 Mac 切换到基于 ARM 的 Mac 的人。

编辑2：我尝试用自己的命令卸载Homebrew arch -x86_64 ./uninstall_brew.sh（我不知道它是否不危险），但我不知道它是否运行良好......

这是命令的输出：

user@MacBook-Pro % arch -x86_64 ./uninstall_brew.sh

尝试运行：PATH=/usr/local/bin:$PATH arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

Answer 2

我在 M1 MBP 上遇到类似的问题，我发现更改脚本中的卸载路径可能会起作用。

首先，我下载卸载脚本的本地副本

curl -O https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh

然后在本地运行脚本并设置路径为/user/local（intel Mac上homebrew的默认路径）

/bin/bash uninstall.sh --path=/usr/local

但它完成时有 2 个警告，我不确定它们是什么

Warning: Failed during: /usr/bin/sudo rmdir /usr/local
Warning: Homebrew partially uninstalled (but there were steps that failed)!
To finish uninstalling rerun this script with `sudo`.
The following possible Homebrew files were not deleted:
/usr/local/Cellar/
/usr/local/Frameworks/
/usr/local/Homebrew/
/usr/local/bin/
/usr/local/etc/
/usr/local/include/
/usr/local/lib/
/usr/local/opt/
/usr/local/sbin/
/usr/local/share/
/usr/local/texlive/
/usr/local/var/
You may wish to remove them yourself.

不管怎样，我都会手动删除这些文件。
