Homebrew在MacOS Big Sur上失败 [英] Homebrew fails on MacOS Big Sur

问题描述

我从莫哈维(Mohave)升级到大苏尔(Big Sur)，发现自制啤酒不再起作用.我使用命令安装了命令行工具

I upgraded from Mohave to Big Sur and found that homebrew is not working any more. I installed the command line tools using the command

xcode-select --install

运行 brew list 后，出现以下错误

~ brew list

我尝试通过删除文件夹/Library/Developer/CommandLineTools 并安装 Xcode 12.3 beta的命令行工具，但仍然遇到相同的错误.有什么方法可以使冲泡工作吗?
