我们正在尝试做一个GitLab runner工作，在某个标记上修改一个版本头文件，并向该变更集添加一个发布分支/标记。
GitLab runner服务器在我的机器上，由我的用户作为服务启动(已正确注册到我们的GitLab服务器(。
GitLab runner job基本上启动了一个使用gitpython来完成作业的python脚本，runner yml文件中只有一些更改(添加了before_script部分以获得上传权限，从那里获得：https://stackoverflow.com/a/55344804/11159476)，这是完整的.gitlab-ci.yml文件：
variables:
GIT_SUBMODULE_STRATEGY: recursive
stages: [ build, publish, release ]
release_tag:
stage: build
before_script:
- git config --global user.name ${GITLAB_USER_NAME}
- git config --global user.email ${GITLAB_USER_EMAIL}
script:
- python .scriptsrelease_gitlab_runner.py
only:
# Trigger on specific regex...
- /^Src_V[0-9]+.[0-9]+.[0-9]+$/
except:
# .. only for tags then except branches, see doc (https://docs.gitlab.com/ee/ci/yaml/#regular-expressions): "Only the tag or branch name can be matched by a regular expression."
- branches
推送时还在python URL中添加了技巧(用user:personal_access_token@repo_URL推送，而不是默认的runner URL，从上面的相同答案中得到，令牌已经从公司gitlab=>user"Settings"=>"Access Tokens"=>"Add a personal Access token"生成，具有所有权限，永远不会过期(，这里是，不是实际的scriptsrelease_gitlab_runner.pypython脚本，而是一个简化为具有尽可能多的git流标准的脚本(获取所有，使用随机名称创建本地分支，使其不存在，修改文件，暂存，提交，最后推送(：
# -*-coding:utf-8 -*
import uuid

# Since we are in <git root path>/scripts folder, git root path is this file's path parent path
GIT_ROOT_PATH = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

versionFileContent.write(patchedVersionFileContent)
print("Stage file")

repo.git.commit("-m", "New version file in new branch {}".format(branchName))

问题
即使使用了拥有权限的技巧，当我们试图从GitLab runner推送时，也会出现以下错误：
Cmd('git') failed due to: exit code(1)
cmdline: git push https://user:token@gitlab.companyname.net/demo/repo.git origin 85a3fa6e-690a-11ea-a07d-e454e8696d31
stderr: 'error: src refspec origin does not match any
error: failed to push some refs to 'https://user:token@gitlab.companyname.net/demo/repo.git''
什么有效
如果我打开一个Git Bash，我成功地运行了手动命令：
git fetch -a
git checkout -b newBranch
vim public/include/Version.h
=> At this point file has been modified
git add -u
git commit -m "New version file in new branch"
git push origin newBranch
在这里，如果我们从其他地方获取所有信息，我们可以看到带有版本文件修改的newBranch
同样，如果我们从python命令行运行脚本内容(不修改URL((假设已经执行了脚本中的所有导入(：
GIT_ROOT_PATH = "E:\path\to\workspace\repo"
branchName = str(uuid.uuid1())
repo = git.Repo(GIT_ROOT_PATH)
repo.git.fetch("-a")
repo.git.checkout("-b", branchName)
versionFile = os.path.join(GIT_ROOT_PATH, "public", "include" , "Version.h")
patchedVersionFileContent = ""
with open(versionFile, 'r') as versionFileContent:
patchedVersionFileContent = versionFileContent.read()
patchedVersionFileContent = re.sub("#define VERSION_MAJOR 0", "#define VERSION_MAJOR {}".format(75145), patchedVersionFileContent)
with open(versionFile, 'w') as versionFileContent:
versionFileContent.write(patchedVersionFileContent)
repo.git.add("-u")
repo.git.commit("-m", "New version file in new branch {}".format(branchName))
repo.git.push("origin", branchName)
结论
在GitLab runner上运行时，我找不到我做错了什么，是不是遗漏了什么？
当我从GitLab runner运行时，我唯一能看到的不同之处是，在获取后，我可以看到我处于一个分离的头上(清单repo.git.branch('-a').split('n')给出了例如['*(head departed at 560976b('，'branchName'，'remotes/origin/otherExistingBranch'，…](，但这应该不是问题，因为我创建了一个新的分支来推送，对吧？
Git说您使用了错误的refspec。当你需要推送其他遥控器时，你必须先将其设为gitlab = repo.create_remote("gitlab", gitlabPushURL)，然后像repo.push("gitlab", branchName)一样推送。
从@glutony编辑为在下一次git运行时不中断"远程已经存在"：
remote_name = "gitlab"
if remote_name not in repo.remotes:
repo.create_remote(remote_name, gitlabPushURL)
