这个问题是关于如何管理对其他私有 gitlab 包具有嵌套依赖关系的私有 gitlab python 包的访问。这假设所有访问都是通过直接 git 存储库模式而不是私有包存储库进行的。

package-a位于私有 gitlab 存储库中，它取决于package-b，这取决于package-c它们也位于私有 gitlab 存储库中。

package-a有pyproject.toml这样的：

[tool.poetry]
name = "package-a"
repository = "https://gitlab.com/org/package_a.git"

[tool.poetry.dependencies]
python = "^3.6"
package-b = {git = "ssh://git@gitlab.com/org/package_b.git", tag = "0.1.0"}

package-b有pyproject.toml这样的：

[tool.poetry]
name = "package-b"
repository = "https://gitlab.com/org/package_b.git"

[tool.poetry.dependencies]
python = "^3.6"
package-c = {git = "ssh://git@gitlab.com/org/package_c.git", tag = "0.1.0"}

任何org在 gitlab 上拥有正确成员资格和 ssh-key 的用户都可以poetry用来安装package-a，它依赖于package-b，然后依赖于package-c，所有这些都在开发笔记本电脑上的 python …

问题的明显解决方案是使用issubclass，但这会引发TypeError（使用 Python 3.6.7），例如

>>> from typing_extensions import Protocol
>>> class ProtoSubclass(Protocol):
...     pass
... 
>>> issubclass(ProtoSubclass, Protocol)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/conda/envs/airflow/lib/python3.6/site-packages/typing_extensions.py", line 1265, in __subclasscheck__
