GitLab runner，推送时出错，而同样的事情在控制台上的 git bash 或 python 上起作用

我们正在尝试做一个 GitLab 运行ner 作业，在某个标记上修改版本头文件并向此变更集添加一个版本 branch/tag。

GitLab 运行ner 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 运行ner 作业基本上启动了一个 python 脚本，该脚本使用 gitpython 来完成作业，只有几个运行ner yml 文件中的更改（添加 before_script 部分以获得上传权限，从那里获得：），这里是完整的 .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 ${GITLAB_USER_EMAIL}
  script:
    - python .\scripts\release_gitlab_runner.py
  only:
    # Trigger on specific regex...
    - /^Src_V[0-9]+\.[0-9]+\.[0-9]+$/
  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

还在 python URL 推送时添加技巧（使用 user:personal_access_token@repo_URL 推送而不是默认运行ner URL，从相同的答案中获得如上所述，令牌已从公司 gitlab => 用户 "Settings" => "Access Tokens" => "Add a personal access token" 生成，拥有所有权利且永不过期），这里是，不是实际的 scripts\release_gitlab_runner.py python 脚本，而是一个简化的 git 流程，尽可能符合我们想要的标准（获取所有内容，创建具有随机名称的本地分支，这样它就不会存在、修改文件、暂存、提交并最终推送):

# -*-coding:utf-8 -*

import uuid
import git
import sys
import os

# 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__)))
try:
    # Get user login and URL from GITLAB_USER_LOGIN and CI_REPOSITORY_URL gitlab environment variables
    gitlabUserLogin = os.environ["GITLAB_USER_LOGIN"]
    gitlabFullURL = os.environ["CI_REPOSITORY_URL"]
    # Push at "https://${GITLAB_USER_NAME}:${PERSONAL_ACCESS_TOKEN}@gitlab.companyname.net/demo/demo.git")
    # generatedPersonalAccessToken has been generated with full rights from https://gitlab.companyname.net/profile/personal_access_tokens and set in a variable not seen here
    gitlabPushURL = "https://{}:{}@{}".format(gitlabUserLogin, generatedPersonalAccessToken, gitlabFullURL.split("@")[-1])
    print("gitlabFullURL is [{}]".format(gitlabFullURL))
    print("gitlabPushURL is [{}]".format(gitlabPushURL))

    branchName = str(uuid.uuid1())

    print("Build git.Repo object with [{}] root path".format(GIT_ROOT_PATH))
    repo = git.Repo(GIT_ROOT_PATH)

    print("Fetch all")
    repo.git.fetch("-a")

    print("Create new local branch [{}]".format(branchName))
    repo.git.checkout("-b", branchName)

    print("Modify file")
    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)

    print("Stage file")
    repo.git.add("-u")

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

    print("Push new branch [{}] remotely".format(branchName))
    # The error is at below line:
    repo.git.push(gitlabPushURL, "origin", branchName)

    sys.exit(0)
except Exception as e:
    print("Exception: {}".format(e))

    sys.exit(-1)

问题

即使使用了拥有权限的技巧，当我们尝试从 GitLab 运行ner 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 Git Bash，我成功运行手动命令：

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内容，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（没有 URL 修改）（假设已执行脚本中的所有导入）：

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

当从 GitLab 运行中运行ning 时，我找不到我做错了什么，是不是我遗漏了什么？

当从 GitLab 运行ner 运行ning 时，我唯一能看到的不同是，在获取之后，我可以看到我在一个分离的头上（列表 repo.git.branch('-a').split('\n') 例如给出 ['* (HEAD detached at 560976b)', 'branchName', 'remotes/origin/otherExistingBranch', ...])，但这应该不是问题，因为我创建了一个新分支推动，对吗？

Git 说你用错了refspec。当您需要推入其他遥控器时，您必须先 gitlab = repo.create_remote("gitlab", gitlabPushURL) 并像 repo.push("gitlab", branchName).

一样推入它

从@gluttony 编辑到下一个 git 运行与 "remote already exists":

不中断

remote_name = "gitlab"
if remote_name not in repo.remotes:
    repo.create_remote(remote_name, gitlabPushURL)
