flask: 报错：ImportError: cannot import name 'secure_filename' from 'werkzeug'

一，报错信息:

$ flask db init
/data/python/flask/panda-sys/venv/lib/python3.10/site-packages/pymilvus/client/__init__.py:6: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.
  from pkg_resources import DistributionNotFound, get_distribution

Usage: flask [OPTIONS] COMMAND [ARGS]...
Try 'flask --help' for help.

Error: No such command 'db'.

二，解决 :

编辑：

/data/python/flask/panda-sys/venv/lib/python3.10/site-packages/flask_uploads.py

注释掉:

# from werkzeug import secure_filename, FileStorage

增加:

from werkzeug.utils import secure_filename
from werkzeug.datastructures import  FileStorage

如下:

# from werkzeug import secure_filename, FileStorage
from werkzeug.utils import secure_filename
from werkzeug.datastructures import  FileStorage
