@Kobayashi 现在 Homebrew 也同样取消了对 macOS 12 Monterey 的支持，所有预编译好的 Bottles (Binary Packages) 都被删掉了。然后随便安装一个什么包都会在本地下载一大堆依赖进行源码编译，一个被依赖的 llvm 包编译安装下来，要用 6 个多小时，真的是非常 buggy and slow 。

接着我也通过 brew uninstall 删除掉了所有的 Homebrew Formulae ，然后同样保留了用 Homebrew Casks 管理本地的 GUI App 。
谁都别跟我说 MacPorts 什么实现的不够优雅，维护的不够好，当被 Homebrew Formulae 完全抛弃之后，MacPorts 就是那个唯一可用的。
而且，根据我的实际使用情况来看，MacPorts 里面绝大多数常用的包的版本都是最新的，安装也很顺滑，完全可以平替 Homebrew Formulae 。执行 sudo port uninstall leaves 命令也能删除掉 uninstall 某个软件包后残余的依赖包。

开源社区用爱发电的确很伟大，但是当爱消失后态度也是很粗鲁的，哈哈。
下面是在 macOS 12 Monterey 上运行 brew 命令后输出的一大段骂骂咧咧的话，各位感受一下语气。
