Question

在python脚本中，我尝试在克隆git存储库后签出标记。我使用GitPython 0.3.2。

#!/usr/bin/env python
import git
g = git.Git()
g.clone("user@host:repos")
g = git.Git(repos)
g.execute(["git", "checkout", "tag_name"])

使用此代码我有一个错误：

g.execute(["git", "checkout", "tag_name"])
File "/usr/lib/python2.6/site-packages/git/cmd.py", line 377, in execute
raise GitCommandError(command, status, stderr_value)
GitCommandError: 'git checkout tag_name' returned exit status 1: error: pathspec 'tag_name' did not match any file(s) known to git.

如果我用分支名称替换标签名称，我没有问题。我没有在GitPython文档中找到信息。如果我尝试在shell中签出相同的标签，我没有问题。

你知道如何在python中签出一个git标签吗？

Answer 1

假设你在'path / to / repo'中克隆了存储库，试试这个：

from git import Git

g = Git('path/to/repo')

g.checkout('tag_name')

Answer 2

from git import Git
g = Git(repo_path)
g.init()
g.checkout(version_tag)

像cmd.py一样，Git评论说

"""
The Git class manages communication with the Git binary.

It provides a convenient interface to calling the Git binary, such as in::

 g = Git( git_dir )
 g.init()                   # calls 'git init' program
 rval = g.ls_files()        # calls 'git ls-files' program

``Debugging``
    Set the GIT_PYTHON_TRACE environment variable print each invocation
    of the command to stdout.
    Set its value to 'full' to see details about the returned values.

这对我有用，我认为它更接近于预期的API用法：

from git import Repo

repo = Repo.clone_from("https://url_here", "local_path")
repo.heads['tag-name'].checkout()
