为什么git checkout“origin/branch-name”在git 1.5中导致“no branch”？

Question

这个问题似乎是由于我对git 1.5的经验不足而产生的，因为如果我尝试使用1.7版本的系统，这种方式工作得很好。为什么我最终选择了“无分支”，更重要的是，我能做些什么才能到达“interesting_branch”的头部？

$ git --version 
git version 1.5.6.5 
git clone [email protected]:path/to/repo 
Initialized empty Git repository in some/local/path/.git 
<snip> 
cd path 
git branch -a 
* master 
    origin/HEAD 
    origin/develop 
    origin/feature-cg-interesting_branch 
$ git checkout feature-cg-interesting_branch 
error: pathspec 'feature-cg-interesting_branch' did not match any file(s) known to git. 
$ git checkout -- feature-cg-interesting_branch 
error: pathspec 'feature-cg-interesting_branch' did not match any file(s) known to git. 
$ git checkout origin/feature-cg-interesting_branch 
Note: moving to "origin/feature-cg-interesting_branch" which isn't a local branch 
If you want to create a new branch from this checkout, you may do so 
(now or later) by using -b with the checkout command again. Example: 
    git checkout -b <new_branch_name> 
HEAD is now at 6534d1d... [Commit message] 
$ git branch 
    * (no branch) 
    master 

Answer 1

您需要手动创建本地跟踪分行：

$ git checkout -b feature-cg-interesting_branch origin/feature-cg-interesting_branch 

你应该做的每一个遥远而明亮的分支除外master

Answer 2

origin/master不是本地分支，因此它留下你的资料库在分离的头部状态（例如，当您通过其哈希签出标签或提交时）。远程分支可以跟踪上一次与远程存储库同步的每个分支的最后状态。

当您想要进一步开发该分支时，您需要创建本地分支。
