不需要自己从git命令中获取数据。GitPython是一种很好的方式来做到这一点，还有很多其他git的东西。它甚至有对Windows的“尽最大努力”支持。

在pip安装gitpython之后你就可以做了

import git
repo = git.Repo(search_parent_directories=True)
sha = repo.head.object.hexsha

使用这个库时需要考虑的一些问题。以下文件摘自gitpython.readthedocs.io

Leakage of System Resources GitPython is not suited for long-running processes (like daemons) as it tends to leak system resources. It was written in a time where destructors (as implemented in the __del__ method) still ran deterministically. In case you still want to use it in such a context, you will want to search the codebase for __del__ implementations and call these yourself when you see fit. Another way assure proper cleanup of resources is to factor out GitPython into a separate process which can be dropped periodically

如果您由于某些原因没有可用的Git，但您有Git repo(。)，你可以从. Git /fetch/heads/[branch]中获取提交哈希。

例如，我在存储库根运行了下面的Python代码片段来获得提交id:

git_head = '.git\\HEAD'

# Open .git\HEAD file:
with open(git_head, 'r') as git_head_file:
    # Contains e.g. ref: ref/heads/master if on "master"
    git_head_data = str(git_head_file.read())

# Open the correct file in .git\ref\heads\[branch]
git_head_ref = '.git\\%s' % git_head_data.split(' ')[1].replace('/', '\\').strip()

# Get the commit hash ([:7] used to get "--short")
with open(git_head_ref, 'r') as git_head_ref_file:
    commit_id = git_head_ref_file.read().strip()[:7]

Numpy在setup.py中有一个漂亮的多平台例程:

import os
import subprocess

# Return the git revision as a string
def git_version():
    def _minimal_ext_cmd(cmd):
        # construct minimal environment
        env = {}
        for k in ['SYSTEMROOT', 'PATH']:
            v = os.environ.get(k)
            if v is not None:
                env[k] = v
        # LANGUAGE is used on win32
        env['LANGUAGE'] = 'C'
        env['LANG'] = 'C'
        env['LC_ALL'] = 'C'
        out = subprocess.Popen(cmd, stdout = subprocess.PIPE, env=env).communicate()[0]
        return out

    try:
        out = _minimal_ext_cmd(['git', 'rev-parse', 'HEAD'])
        GIT_REVISION = out.strip().decode('ascii')
    except OSError:
        GIT_REVISION = "Unknown"

    return GIT_REVISION

这是对富田裕治‘富田’的改进回答。

import subprocess

def get_git_revision_hash():
    full_hash = subprocess.check_output(['git', 'rev-parse', 'HEAD'])
    full_hash = str(full_hash, "utf-8").strip()
    return full_hash

def get_git_revision_short_hash():
    short_hash = subprocess.check_output(['git', 'rev-parse', '--short', 'HEAD'])
    short_hash = str(short_hash, "utf-8").strip()
    return short_hash

print(get_git_revision_hash())
print(get_git_revision_short_hash())

我遇到了这个问题，并通过实现这个函数解决了它。 https://gist.github.com/NaelsonDouglas/9bc3bfa26deec7827cb87816cad88d59

from pathlib import Path

def get_commit(repo_path):
    git_folder = Path(repo_path,'.git')
    head_name = Path(git_folder, 'HEAD').read_text().split('\n')[0].split(' ')[-1]
    head_ref = Path(git_folder,head_name)
    commit = head_ref.read_text().replace('\n','')
    return commit


r = get_commit('PATH OF YOUR CLONED REPOSITORY')
print(r)

git describe命令是创建适合人类的代码“版本号”的好方法。参考文档中的例子:

和像少年犯一样的东西。git当前树，我得到: [torvalds@g5 git]$ git描述父 v1.0.4-14-g2414721 例如，我的“父”分支的当前头基于v1.0.4，但由于它在此之上有一些提交，describe在最后添加了额外提交的数量(“14”)和提交本身的缩写对象名称(“2414721”)。

在Python内部，你可以做如下的事情:

import subprocess
label = subprocess.check_output(["git", "describe"]).strip()
