Reason is incompatible with newly released Werkzeug . You need to install werkzeug==0.16.1 and also connexion. Hope this helps!
Very useful, thanks!
For those who are struggling with 'ImportError: cannot import name 'secure_filename', just install Flask-Reuploaded and the error message will be gone.
https://pypi.org/project/Flask-Reuploaded/
Since the hashed filename isn't used for any purpose other than uniqueness, you could replace it with something like str(uuid.uuid4()) and achieve the same goal
@tassaron2 Updated, thanks for the tip.

It will introduce other errors to this project from what I tested.
