我怎么能叫'git的拉'从内部的Python？ [英] How can I call 'git pull' from within Python?

问题描述

使用GitHub的网络挂接，我希望能拉的任何更改到远程开发服务器。此刻，当相应的目录， git的拉获取需要进行任何更改。但是，我想不出如何调用该函数从Python中。我曾尝试以下内容：

Using the github webhooks, I would like to be able to pull any changes to a remote development server. At the moment, when in the appropriate directory, git pull gets any changes that need to be made. However, I can't figure out how to call that function from within Python. I have tried the following:

import subprocess
process = subprocess.Popen("git pull", stdout=subprocess.PIPE)
output = process.communicate()[0]

但是，这将导致以下的错误

But this results in the following error

      提高child_exception OSERROR：[错误2]没有这样的文件或目录

有没有办法，我可以从Python中调用这个bash命令的方式？

Is there a way that I can call this bash command from within Python?

推荐答案

你有没有考虑过使用GitPython？它的设计处理了这么多废话你。

Have you considered using GitPython? It's designed to handle all this nonsense for you.

import git 

g = git.cmd.Git(git_dir)
g.pull()
