如何使用GitPython拉取远程存储库？

Question

我正在尝试找到使用gitPython拉取git存储库的方法。到目前为止，这是我从官方文档here中获取的内容。

test_remote = repo.create_remote('test', 'git@server:repo.git')
repo.delete_remote(test_remote) # create and delete remotes
origin = repo.remotes.origin    # get default remote by name
origin.refs                     # local remote references
o = origin.rename('new_origin') # rename remotes
o.fetch()                       # fetch, pull and push from and to the remote
o.pull()
o.push()

事实上，我想在不重命名其原点(origin.rename)的情况下访问repo.remotes.origin来执行拉操作，我如何才能做到这一点？谢谢。

Answer 1

我通过直接获取repo名称来做到这一点：

 repo = git.Repo('repo_path')
 o = repo.remotes.origin
 o.pull()

Answer 2

希望你正在寻找这个：

import git
g = git.Git('git-repo')
g.pull('origin','branch-name')

拉取给定存储库和分支的最新提交。

正如公认的答案所说，可以使用repo.remotes.origin.pull()，但缺点是它将真正的错误消息隐藏在它自己的通用错误中。例如，当DNS解析不起作用时，repo.remotes.origin.pull()会显示以下错误消息：

git.exc.GitCommandError: 'Error when fetching: fatal: Could not read from remote repository.
' returned with exit code 2

另一方面，像repo.git.pull()这样的using git commands with GitPython显示了真正的错误：

git.exc.GitCommandError: 'git pull' returned with exit code 1
stderr: 'ssh: Could not resolve hostname github.com: Name or service not known
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.'
