如何在AWS Lambda中安装pydantic库？

Question

我正在从事一个使用无服务器框架、Flask 和 MongoDB 开发的项目。问题是当我尝试安装 pydantic 时，在回溯中说ModuleNotFoundError：没有名为 'pydantic_core._pydantic_core' 的模块，但在我的要求中指定了库。

是否有安装 pydantic 的表格，或者无法在 Lambda 的 AWS 中安装该库？

Cloudwatch 中的追溯

File "/var/task/app.py", line 5, in <module>
from pydantic import ValidationError
File "/var/task/pydantic/__init__.py", line 3, in <module>
import pydantic_core
File "/var/task/pydantic_core/__init__.py", line 6, in <module>
from ._pydantic_core import (
ModuleNotFoundError: No module named 'pydantic_core._pydantic_core'
[ERROR] Exception: Unable to import app.app
Traceback (most recent call last):
  File "/var/lang/lib/python3.11/importlib/__init__.py", line 126, in import_module

  File "/var/task/wsgi_handler.py", line 115, in <module>
    wsgi_app = import_app(config)
  File "/var/task/wsgi_handler.py", line 48, in import_app
    raise Exception("Unable to import 
{}
".format(config["app"]))

我尝试过降级 python、pydantic、Flask 的版本。我还指定了库 pydantic_core 但不起作用。
