Authentication in gitpython

问题

I am trying to write a fairly simple function (I thought).

I want a user to specify a path to a checked out git repo on his computer. (A git repo that requires authentication).

I then want to do a git pull on that folder to grab any changes.

My code looks like this:

    import git
    repo=git.cmd.Git(GIT_PATH)
    repo.pull()

This works perfectly on my Linux machine, it never asks for any credentials (I am guessing because ssh-agent has already unlocked the key and supplies credentials when my script needs it).

On Windows however, I can't get it to to work. I have installed putty and added the key to pageant. I can check out the repo using TortoiseGit for example and it works perfectly fine, but if I execute the code above on the Windows machine, I get:

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    repo = git.repo.base.Repo.clone_from(GIT_PATH, "t
mp")

   return cls._clone(Git(os.getcwd()), url, to_path, GitCmdObjectDB, progress,
**kwargs)

Permission denied (publickey,password).
fatal: Could not read from remote repository.

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

Edit: I would like to add that I am not married to GitPython. If anyone knows of another library that would solve my problem, that would work as well.
