Bug:AttributeError: module 'pydantic._migration' has no attribute 'JsonValue' about litestar HOT 5 CLOSED

Hi @kodecreer, thanks for reporting!

I cannot reproduce this as of now with the dependencies you specified on Python 3.10. That being said though, I have only tested it on Linux, but I don't think that would make a difference 👓

Just to confirm, this is the code you're running?

from litestar import Litestar, get


@get("/")
async def hello_world() -> str:
    return "Hello, world!"


app = Litestar([hello_world])

from litestar.

Yes that's the exact code I ran. Python version is 3.10.5

from litestar.

Ok found out the issue. Litestar for some reason doesn't work with Python version 3.10.5 on Mac. It's reccomended to use a different version of python . I am here if you prefer to continue investigating the cause of this issue. I updated my python version to 3.12 and it worked fine.

Recommended by whom? 👀

Is this some dependency resolution thing?
If yes, how have you installed Litestar?

from litestar.

By me because it fixed my issue on my Mac and in case someone runs into the same issue in the future.

Probably something in the implmentation of Python on Mac. Forgot to mention it's monterey OSX
I installed it using "pip install litestar[standard]"
