无法更新或升级Homebrew。

Question

我无法再运行brew upgrade或者brew update了：两者都会中途停止。

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

如果我按照这个建议运行 git ... --unshallow 然后尝试 brew update 或者 brew upgrade，我仍然会得到相同的错误信息。

如果我再次尝试该命令（也许第一次没有做对？），我会得到以下错误：

fatal: --unshallow on a complete repository does not make sense

如何绕过此错误消息，以在没有错误的情况下运行brew upgrade或brew update?

Answer 1

它要求你同时使用以下命令取消浅层克隆 homebrew-core和 homebrew-cask ：

git -C "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core" fetch --unshallow
git -C "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask" fetch --unshallow

它解决了我的问题。现在'bew upgrade && brew upgrade --cask'可以正常工作了。谢谢。 - frekele

在我的情况下，只有第一个命令被请求以获取brew update。 - Andrea Leganza

当我尝试运行 git homebrew-core 命令时，出现以下错误：fatal: the remote end hung up unexpectedly fatal: protocol error: bad pack header 有什么想法吗？ - Ricardo Sanchez

可能是您的连接出了问题，所以请重新运行命令。如果问题仍然存在，请尝试使用 brew update-reset 命令。 - Eric3

@RicardoSanchez 这些仓库非常大，我也遇到了同样的问题。在 git 命令后加上 verbose 参数（-v），你应该会在一段时间后看到一些进展。git -C "/path/to/repo" fetch --unshallow -v - Cesar Zapata

Answer 2

直到我做了以下的事情，才让一切开始顺利：

cd /usr/local/Homebrew/Library/Taps/homebrew/
rm -rf homebrew-core
git clone https://github.com/Homebrew/homebrew-core.git

注意：对于基于 ARM 的 Mac，Homebrew Taps 现在位于：/opt/homebrew/Library/Taps/homebrew

fetch --unshallow 会卡住，这个方法对我有效。 - ir2pid

Answer 3

似乎Homebrew政策发生了变化，不再进行浅拷贝。

正确的答案是unshallow，如Eric3答案所述，或重新安装，这将产生一个非浅拷贝/常规库的副本。

这对我有用。
