This repository is no longer maintained.

Please switch to the compatible APITable Python SDK:
https://github.com/apitable/apitable-sdks/tree/develop/apitable.py

APITable is the open-source version of Vika, and its Python SDK stays API-compatible with vika.py.

Thanks for the report. Root cause: vika.py is still on pydantic v1, and Python 3.14 removed the type-inference path v1 relied on for bare Any = None annotations, so class MetaField(BaseModel) fails at import time. Since this repo is no longer maintained, we won't be patching it upstream.

Please switch to the maintained SDK, which is pydantic v2 based and API-compatible: https://github.com/apitable/apitable-sdks/tree/develop/apitable.py

# before
from vika import Vika
vika = Vika(token)

# after
from apitable import Apitable
apitable = Apitable(token)

Note: the current apitable release pins pydantic to an exact 2.5.3, which also has no wheel for Python 3.14. I've opened apitable/apitable-sdks#128 to loosen the pin and fix a related MetaField crash — once that ships, 3.14 installs cleanly.
