How to checkout a tag with GitPython
In a python script, I try to checkout a tag after cloning a git repository. I use 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"])
With this code I have an error:
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.
If I replace the tag name with a branch name, I have no problem. I didn't find informations in GitPython documentation. And if I try to checkout the same tag in a shell, I have non problem.
Do you know how can I checkout a git tag in python ?
Answer
Assuming you cloned the repository in 'path/to/repo', just try this:
from git import Git
g = Git('path/to/repo')
g.checkout('tag_name')
