如果您有一个使用--depth 1克隆的存储库，那么列出的许多命令将无法工作。例如，请参见此处

% git clone --depth 1 https://github.com/repo/code

在这种情况下，我会重新克隆存储库，但可能还有其他技术，例如git浅层克隆（clone--depth）错过了远程分支

git fetch&&git checkout<你朋友的分行名>应该可以做到这一点

一个简单的命令gitcheckoutremote_branch_name将帮助您创建一个本地分支，该分支包含远程分支中的所有更改。

您也可以一次获取并签出远程分支：

git fetch && git checkout the-branch-name

如果你已经知道你的远程分支了。。。

git remote
=> One
=> Two

并且您知道要签出的分支名称，例如br1.2.3.4，然后执行

git fetch One
=> returns all meta data of remote, that is, the branch name in question.

剩下的就是结账

git checkout br.1.2.3.4

然后用它做新的树枝。

如果下载带有git clone<repo_url>-b<branch>（仅克隆特定分支）的存储库，则应修改<repo_name>/.git/config文件。替换或修改引用[remote“origin”]部分的fetch目标的行，让命令git fetch--all发现所有分支：

[remote "origin"]
        url = <repo_git_url>
        fetch = +refs/heads/master:refs/remotes/origin/master

确保将提取参数点设置为/heads/master。

小心git fetch，因为这会获取所有数据，所以可能需要很长时间。
