Spacy dependency requirements are not met for pydantic versions ^2

[jacobmanderson]

How to reproduce the behaviour

Example pyproject.toml

[tool.poetry.dependencies]
python = "^3.7"
pydantic = "^2.0.0"
spacy = "^3.2.0"

When running poetry update --lock there is a build dependency error between pydantic version ^2 and typing-extensions.

And because spacy (3.7.2) depends on typing-extensions (>=3.7.4.1,<4.5.0)
 and pydantic (2.0) depends on typing-extensions (>=4.6.1), pydantic (2.0) is incompatible with spacy (>=3.2.0,<4.0.0).

The restriction on typing-extensions is in the requirements.txt, which are run via setuptools in pyproject.toml

It's difficult to support+test every possible combination of requirements and we've had trouble with older versions of pydantic and newer versions of typing_extensions in the past.

In this case I'd strongly suggest using python 3.8+, where typing_extensions is no longer a requirement for spacy. It's only needed for python 3.7 and earlier for backports.
