pydantic: Pydantic 1.10.3 incompatible with typing-extensions 4.1.1

Initial Checks

• I have searched GitHub for a duplicate issue and I’m sure this is something new
• I have searched Google & StackOverflow for a solution and couldn’t find anything
• I have read and followed the docs and still think this is a bug
• I am confident that the issue is with pydantic (not my code, or another library in the ecosystem like FastAPI or mypy)

Description

• Installed latest pydantic and typing-extensions 4.1.1
• Code crashes on import pydantic

I suspect we just need to bump the min version requirement or fix a cross-version incompatibility, since it works with typing-extensions 4.4.0.

Example Code

# Set up a clean venv
# pip install pydantic==1.10.3 typing-extensions==4.1.1

>>> import pydantic
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pydantic/__init__.py", line 2, in init pydantic.__init__
  File "pydantic/dataclasses.py", line 46, in init pydantic.dataclasses
    # | None    | Attribute is set to None.               |
  File "pydantic/main.py", line 121, in init pydantic.main
TypeError: dataclass_transform() got an unexpected keyword argument 'field_specifiers'

Python, Pydantic & OS Version

Crashes so I can't run that

Tested with python 3.7.9

Affected Components

• Compatibility between releases
• Data validation/parsing
• Data serialization - .dict() and .json()
• JSON Schema
• Dataclasses
• Model Config
• Field Types - adding or changing a particular data type
• Function validation decorator
• Generic Models
• Other Model behaviour - construct(), pickling, private attributes, ORM mode
• Plugins and integration with other tools - mypy, FastAPI, python-devtools, Hypothesis, VS Code, PyCharm, etc.
