git - Pathspec upstream/master 不明确

Question

我可以推送、 pull 和检查上游/master 一点问题都没有，但我确实收到警告。Upstream/master 用于跟踪对我 fork 的原始源代码所做的更改(已遵循 github 说明)。

例如

$ git checkout upstream/master
warning: refname upstream/master is ambiguous

$ git branch -a
* master
  upstream/master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
  remotes/upstream/master

这个命令也有不明确的错误:

$ git branch
* master
  upstream/master

$ git checkout upstream/master filename.bar

This page提到了此类消息的常见原因:

When you try to checkout a local branch, you get a

warning: refname 'branch-name' is ambiguous

This can happen if you've created a local branch with the same name as a remote tag.
Git should be checking out your local branch, but instead it's trying to checkout the tag, and it gets confused.

In general, when creating tags, be careful not to have names that conflict with existing (local or remote) branches.
