Pydantic 1.10.3 incompatible with typing-extensions 4.1.1 #4885
Description
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):

Crashes so I can't run that
