Fresh installation of 2.0.1 seems broken

[nathan-mill]

Added Flower to a Django app via poetry add flower. venv is properly activated. Everything else in the project works exactly as expected.

Flower Package is present and accounted for:

% ls .venv/lib/python3.11/site-packages/flower

That very same site-packages directory IS included in the sys.path of the very same interpreter binary that is executing everything else in the venv.

Output from the attempt at printing a bug report:

% python -c 'from flower.utils import bugreport; print(bugreport())'                                                                                                                                              
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'flower.utils'

Immediate crash when I try to run Flower:

% celery -A myapp flower

I've wiped out the venv and all pycache folders and .pyc files repeatedly. I always wind up in this state again after poetry install. Wiped out the entire repository and cloned it over from scratch. Somehow, Flower gets installed in the same place as every other working dependency, yet is not actually usable in any way.

Downgrading from 2.0.1 to 2.0.0 seems to make it work.

I'm not able to reproduce this. Version 2.0.1 works in a new virtual environment

[nathan-mill]

The problem persists here. Are you installing via Poetry in your testing?

[mher]

I tried with pipenv
