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

[manuel-masiello]

Good morning.

Thank you for this example code, however I have errors that I cannot correct :

$ conda create --name test-libs
$ conda activate test-libs
$ conda install pip
$ pip install flask flask-uploads flask-dropzone
$ export FLASK_APP=app.py
$ flask run

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

Error: While importing 'app', an ImportError was raised:

Traceback (most recent call last):
