可以运行demo_toolbox.py，运行web.py报错

**Summary[问题简述（一句话）]**
A clear and concise description of what the issue is.
cmd运行demo_toolbox.py正常使用，cmd运行web.py报错：

PydanticImportError: `pydantic:parse_raw_as` has been removed in V2.

python用的3.10.11版本，其他都是按照安装指导装的，有更新的自己更新了。

**Screenshots[截图（如有）]**

Start with web.py and reproduce the reported PydanticImportError while comparing the installed packages with the installation guide. Check how web.py uses pydantic:parse_raw_as and confirm the expected dependency setup; done means web.py runs without this error under the documented Python 3.10.11 environment.
