git checkout -b branch_name
git pull remote_name branch_name

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

git branch＜name＞--跟踪原点/＜name＞

检查.git/config文件，特别是该远程设备的fetch跟踪。

[remote "randomRemote"]
    url = git@github.com:someUser/someRepo.git
    fetch = +refs/heads/*:refs/remotes/randomRemote/*

如果头/*指向randomRemote/*，当您运行gitfetchrandomRemote时，它将获取所有分支。

然后你就可以结账了。

否则

您需要使用此命令将远程分支添加到跟踪中。运行此命令后，请检查.git/config。你会明白的。git remote set branches--add randomRemote randomBranch运行git fetch randomRemote。这将获取远程分支。现在您可以运行git checkout randomBranch。

您也可以一次获取并签出远程分支：

git fetch && git checkout the-branch-name

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
