black posthook throws `ImportError: cannot import name 'izip_longest' from 'pathspec.compat'`

首先，根据列出的 Python 3.9 依赖项复现 Poetry 环境，并运行 openapi-python-client update，随后运行 black .。检查依赖项解析以及 Black/pathspec 导入失败的问题；当 post hook 和随后单独运行的 black . 都无错误完成时，即视为完成。

Describe the bug
During the black . post hook, openapi-python-client throws :

openapi-python-client update --url someurl.com/openapi.json

Updating my_project
Error(s) encountered while generating, client was not created
black failed

ImportError: cannot import name 'izip_longest' from 'pathspec.compat' (C:\Users\x\code\my_project\venv\lib\site-packages\pathspec\compat.py)

In a fresh environment, running black . on my own works originally. Then, running openapi-python-client update fails at the black step. Then, the strange thing is that this error persists when running black . on my own afterwards.

To Reproduce
Steps to reproduce the behavior:

1. Install dependencies as listed in Desktop section, using poetry
2. Run openapi-python-client update
3. See error during black post hook.

Expected behavior
I expect the black . to complete without errors.

OpenAPI Spec File
Unfortunately this is under NDA. However, the package is generated without issue, the problem comes from the black post hook.
