升级到macOS11之后，我的自制版就不工作了。
和brew update一起，我得到了

我也有过同样的问题。我用这个博客解决了这个问题。
- 删除旧的xcode命令行工具
sudo rm -rf /Library/Developer/CommandLineTools - 安装新的xcode命令行工具
sudo xcode-select --install - 更新brew (注意:您可能需要运行两次)
brew upgrade - 如果仍然收到错误消息，请尝试通过以下方法重新安装brew：
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" - 测试brew是否有效
