I've been using poetry for a while for many practice projects but haven't deployed anything until now, and when I try to do it in heroku I get this error.

I can't seem to find anything specific to this django-poetry-heroku issue so maybe I can find some help over here, I have my petry.lock and .toml files, also a requirements.txt since heroku requires it, here they are...

pyproject.toml
[tool.poetry]
name = "Team Wool Capstone App"
version = "0.1.0"
description = "News app with likes, and user submission feature"
authors = ["Joseph Dubon <josephdubon@pm.me>"]

[tool.poetry.dependencies]
python = "^3.9"
Django = "^3.1.7"
flake8 = "^3.9.0"
Pillow = "^8.2.0"
whitenoise = "^5.2.0"
django-environ = "^0.4.5"
gunicorn = "^20.1.0"

[tool.poetry.dev-dependencies]

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"
python-poetry heroku deployment django python

Are you using the heroku buildpack for poetry? Heroku only reads requirements.txt files when building python projects, and you will need to set multiple config vars and explicitly tell heroku to use the poetry buildpack.

heroku buildpacks:clear
heroku buildpacks:add https://github.com/moneymeets/python-poetry-buildpack.git
heroku buildpacks:add heroku/python

The Heroku platform yet does not run with Poetry.

To deploy your Django application you'll need to use the Pip, Pip3, or Pipenv tools.
To use Pip/Pip3 you need to export your pyproject.toml file to a requirements.txt file.

The Poetry has a command for this, which is (see the docs on Poetry):

poetry export -f requirements.txt --output requirements.txt
