FLASK_APP=app.py FLASK_DEBUG=1 SQLALCHEMY_DATABASE_URI=sqlite:///tmp/test.db flask current
Usage: flask [OPTIONS] COMMAND [ARGS]...

So, I followed the instructions on the readme...
git clone https://github.com/juriansluiman/groceri.es.git
cd groceri.es
(on second try I do git fetch origin pull/25/head:pr-25 && git checkout pr-25 here)
python3 -m venv ve
source ve/bin/activate
pip install -r app/requirements.txt
cd app/
FLASK_APP=app.py FLASK_DEBUG=1 SQLALCHEMY_DATABASE_URI=sqlite:///tmp/test.db flask current

and it errors

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

Error: No such command 'current'.

So, what am I missing or is this a bug?
