brew tap facebook/fb 导致获取错误

Question

我尝试像往常一样更新 Homebrew。最近当我发出命令 brew update 时，出现以下错误：

Error: Fetching /usr/local/Homebrew/Library/Taps/facebook/homebrew-fb failed!

Tap 与我开发需要的软件 Buck 相关联。

我按照Buck官网的installation instruction进一步排查问题，再次下命令：

% brew tap facebook/fb
==> Unshallowing facebook/fb
fatal: couldn't find remote ref refs/heads/master
Error: Failure while executing; `git fetch --unshallow` exited with 128.

显然，Git 来源有问题。我尝试“重置”它：

% brew untap facebook/fb
Error: Refusing to untap facebook/fb because it contains the following installed formulae or casks:
buck

运气不好。我该如何解决这个问题？

Answer 1

此错误是 Facebook 将分支 master 重命名为 main 的结果。

要解决此问题，请先切换到 Homebrew 的本地 tap 文件夹：

cd /usr/local/Homebrew/Library/Taps/facebook/homebrew-fb

然后，运行以下Git命令更新本地仓库：

git branch --unset-upstream
git config remote.origin.fetch '+refs/heads/main:refs/remotes/origin/main'
git fetch --prune origin
git branch -m main
git branch -u origin/main
git remote set-head origin -a

最后，删除不再需要的 master ref（可选）：

rm .git/refs/remotes/origin/master

就是这样，您现在应该可以成功运行 brew update.
