要获取远程上存在的分支，最简单的方法是：

git fetch origin branchName
git checkout branchName

您可以通过以下方式查看它是否已存在于远程：

git branch -r

这会将远程分支提取到本地，并自动跟踪远程分支。

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
Cloning into '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

我键入了

git checkout <branch_name>

并且得到

Branch <branch_name> set up to track remote branch <branch_name> from origin.
Switched to a new branch '<branch_name>'

git checkout -b branch_name
git pull remote_name branch_name

git fetch--all&git checkout<分支名称>

使用此简单命令：

git checkout -b 'your_branch' origin/'remote branch'
