flask-script only works with ancient flask

[miiichael]

Expected behaviour

A working Flask example, to help noobs like me...

Actual behaviour

ModuleNotFoundError: No module named 'flask._compat'

What are the steps to reproduce this issue?

git clone https://github.com/python-social-auth/social-examples cd social-examples/example-flask python3 manage.py

Any logs, error output, etc?

Traceback (most recent call last):
  File "/mnt/home/michael/docs/dev/social-examples/example-flask/manage.py", line 3, in <module>
    from flask_script import Manager, Server, Shell

    from flask._compat import text_type
ModuleNotFoundError: No module named 'flask._compat'

Any other comments?

Expand the issue with any details you find appropriate to solve or reproduce it.

I have these installed.

Flask                            2.2.2
Flask-Breadcrumbs                0.5.1
Flask-Login                      0.6.2
flask-menu                       1.0.1
Flask-Migrate                    4.0.4
Flask-Script                     2.0.6
Flask-SQLAlchemy                 3.0.3
social-auth-app-flask            1.0.0
social-auth-app-flask-sqlalchemy 1.0.1
social-auth-core                 4.5.3
social-auth-storage-sqlalchemy   1.1.0

Also note the warning at the top of https://flask-script.readthedocs.io/en/latest/:

the error you're encountering indicates that the flask_script package is trying to import a module (flask._compat) that no longer exists in the latest versions of Flask. This is likely due to the flask_script package being outdated.

Here are a few ways to resolve this issue:

Update to Flask-Script2: Flask-Script is no longer maintained. A fork called Flask-Script2 is available, which might resolve the issue.

First, uninstall flask_script:

pip uninstall flask_script

Then, install Flask-Script2:

pip install Flask-Script2

Add some necessary chances

[miiichael]

pip install Flask-Script2

Wow, I smell LLM.

michael@foo:~/dl$ pip download Flask-Script2
ERROR: Could not find a version that satisfies the requirement Flask-Script2 (from versions: none)
ERROR: No matching distribution found for Flask-Script2

And/or an incompetent attempt at supply chain attack...

Indeed, that comment looks weird. Anyway: https://github.com/python-social-auth/social-examples/pull/50 most likely addresses this issue, but lacks review.
