git pull 上的 Git 错误(无法更新本地引用)

Question

我只有 branch master 并且我每次尝试“git pull”时都会收到此错误:

error: Couldn't set refs/remotes/origin/master
From /var/lib/git/xxx/project
 ! a0f80ea..49177a3  master     -> origin/master  (unable to update local ref)

当我执行“git pull origin master”时，我得到:

error: Couldn't set ORIG_HEAD
fatal: Cannot update the ref 'ORIG_HEAD'.

我一直在寻找，但找不到原因

Answer 1

我和我的团队遇到了这个错误，无法更新本地引用，当在 SourceTree 中 pull 时。

Update 2020: Per @Edward Yang's answer below, @bryan's comment on this answer, and this question/answer you may need to run both git gc --prune=now and git remote prune origin. Running only the former has always worked for me but based on ppl's responses I think both are necessary to address different causes of the error.

我们使用了:

git gc --prune=now

这会删除任何重复的引用对象，这应该可以解决问题。
