我的剧本需要能够支持在执行生产部署时向 github 存储库添加标签。目的是通过 Ansible 的内置 github_release 模块自动生成发布标签，作为 Ansible 服务器上的本地操作。该模块的文档很清楚，并且直截了当，该模块需要 github3.py Python 模块。

我现在遇到的问题是我们的“CICD 操作员”不相信 github3.py 模块需要安装在 Ansible 服务器上。信念是“github3.py”可以放入 /library 目录，并且无论在哪个服务器上运行该模块都可用。基于我对 Ansible playbook 库的有限理解，这似乎是合乎逻辑的；但是，github3 不仅仅是一个可以复制到目录中的简单 Python 脚本。

我发现的一切都表明这需要通过 PIP 安装在服务器上。这是做到这一点的唯一方法，还是我错过了一些基本过程来获取源 tar 球并将其添加为本地剧本库？我尝试将源代码提取到 ./library，甚至创建了指向结构中不同点的符号链接。

您可以让 playbook 将必要的依赖项安装到临时 virtualenv 中，然后使用 playbook 的其余部分针对该 venv 执行：

- hosts: localhost
  connection: local
  tasks:
  - raw: |
     if [ -x /tmp/bob/bin/python ]; then exit 0; fi
     /usr/local/bin/python3 -m venv --prompt tmp /tmp/bob
     .  /tmp/bob/bin/activate
     /tmp/bob/bin/pip install --upgrade 'github3.py >= 1.0.0a3'

- hosts: localhost
  connection: local
  vars:
    ansible_python_interpreter: /tmp/bob/bin/python
  tasks:
  - github_release:
      user: ansible
      repo: ansible
      action: latest_release

（替换你自己的hosts:and connection:；我只是使用 localhost 和 local 来测试这样的事情是否可行，以及它的答案）

甚至可以在一个角色中做这样的事情，进行一些清理行动或其他什么，但我没有走那么远
