_pygit2.GitError: authentication required but no callback set

I'm guessing this is an issue on my end, not really an issue with pygit2, but I've been stuck on it for two days with almost no progress and the documentation isn't making sense to me.

I am trying to push to a repository using user name and password credentials and getting the error:

File "createRepo.py", line 72, in remote.push(['refs/heads/master']) File "/usr/local/lib/python2.7/dist-packages/pygit2/remote.py", line 470, in push check_error(err) File "/usr/local/lib/python2.7/dist-packages/pygit2/errors.py", line 64, in check_error raise GitError(message) _pygit2.GitError: authentication required but no callback set

```
#Clone the newly created repo
repoClone = pygit2.clone_repository(repo.git_url, '/var/www/html/uploads/tmp')
print "GIT URL: "
print repo.clone_url
print "<---"

#Add the new files to the repo
for file in files:
    os.rename("/var/www/html/uploads/" + file, "/var/www/html/uploads/tmp/" + file)

#Commit it
repoClone.remotes.set_url("origin", repo.clone_url)
index = repoClone.index
index.add_all()
index.write()
author = pygit2.Signature("MaslowCommunityGardenRobot", "info@maslowcnc.com")
commiter = pygit2.Signature("MaslowCommunityGardenRobot", "info@maslowcnc.com")
tree = index.write_tree()
oid = repoClone.create_commit('refs/heads/master', author, commiter, "init commit",tree,[repoClone.head.get_object().hex])
remote = repoClone.remotes["origin"]
credentials = pygit2.UserPass(userName, password)
remote.credentials = credentials
remote.push(['refs/heads/master'])

The documentation clearly says that there is an optional callback argument push(specs, callbacks=None), but how and when to use that feature is not clear.

If I can get this to work I will post it as a clear, simple example of how to create a repository with pyGitHub, clone it, create a commit, and push it which is something I think is missing.

从 createRepo.py 第 72 行附近以及 pygit2 remote.push(specs, callbacks=None) 文档开始，然后将 UserPass 赋值与 callback API 进行比较。确定是否缺少身份验证指南或示例，并在所需的 push 身份验证流程得到明确记录或演示后，将 issue 视为完成。
