如何解决无法更新或升级 Homebrew

我无法再运行 brew upgrade 或 brew update：两者都中止

Error: homebrew-core is a shallow clone. To `brew update` first run:
  git -C "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core" fetch --unshallow
and if I follow this suggestion and run git ... --unshallow

如果我按照这个建议运行git ... --unshallow，然后尝试brew update 或brew upgrade，我仍然会收到相同的错误消息。

如果我再次尝试该命令（也许我第一次没有做对？）我得到

fatal: --unshallow on a complete repository 没有意义

如何通过此错误消息运行brew upgrade 或brew update 而不会出现错误？

【问题讨论】：

你的意思是，你运行git -C "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core" fetch --unshallow，你还有问题吗？

【解决方案1】：

基本上，如果您看到以下错误，则运行提示您的内容，但可能需要 5 到 10 分钟，具体取决于您的系统速度：

Error:
  homebrew-core is a shallow clone.
  homebrew-cask is a shallow clone.
To `brew update`, first run:
  git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
  git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow

我希望能回答你或其他人的问题，祝你好运。
