I'm trying to deploy a django application but I keep getting this error:

ModuleNotFoundError: No module named 'django_project.wsgi'

In fact, here's the full log:

Here's my Procfile

web: gunicorn django_project.wsgi:application --log-file - --log-level debug
python manage.py collectstatic --noinput
manage.py migrate

On settings.py I have the following:

ALLOWED_HOSTS = [
    '127.0.0.1',
    'django-blog-project-laila.herokuapp.com'
]

MIDDLEWARE = [
    ...
    'whitenoise.middleware.WhiteNoiseMiddleware',
    ...
]

Here's my wsgi.py file:

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'django_project.settings')

application = get_wsgi_application()

Here's my project strucure:

enter image description here

I've tried moving Procfile to the same folder as the manage.py file, but then heroku can't locate it.

Here's the log when Procfile is located at the same folder as manage.py:

Edit: With Procfile still at manage.py folder, I've tried the command heroku local web to see if I can run it locally. But I get the following error:

[WARN] ENOENT: no such file or directory, open 'Procfile'
[FAIL] No Procfile and no package.json file found in Current Directory - See run-foreman.js --help

I've tried changing Procfile to the following:

web:gunicorn django_project.wsgi --log-file -

But nothing.

Tried running heroku local web with Procfile in the same level as my git repository (which I'm refering to as the root directory, which is one level above my manage.py file) but same error:

[WARN] ENOENT: no such file or directory, open 'Procfile'
[FAIL] No Procfile and no package.json file found in Current Directory - See run-foreman.js --help

What am I doing wrong? Any help is appreciated. Thank you.

Add runtime.txt with your python version

runtime.txt

python-"your version"

and run

pip freeze > requirements.txt

  • I've tried adding a `runtime.txt` file but I still get the same error. And isn't a `requirement.txt` file unnecessary since I already have a `Pipfile` and `Pipfile.lock`? I'm basing myself on [this](https://stackoverflow.com/a/60467318/11627241) answer for the last bit. – Laila Campos May 13 '22 at 16:54
  • Oh, you right requirements.txt and Pipfile are the same. May be try `web: gunicorn django_project.wsgi--log-file - --log-level debug` without `:application` Like [here](https://docs.djangoproject.com/en/4.0/howto/deployment/wsgi/gunicorn/) – Ivan S May 13 '22 at 17:09
  • Tried it without `:application` but it didn't work. I still get the same error. – Laila Campos May 13 '22 at 17:35
  • May be something with path to wsgi. Try `cd .. && gunicorn project.wsgi:application` or `cd ./project && gunicorn myproject.wsgi:application`. I have no more ideas. – Ivan S May 13 '22 at 17:56

First off, make sure your Procfile, requirements.txt & runtime.txt files are in the same folder as the manage.py file.

Your Procfile should read as follows: web:gunicorn django_project.wsgi --log-file -

Your runtime.txt should read as follows: python-versionnumber. e.g. python-3.10.2

Your requirements.txt file is necessary as it helps heroku resolve and install packages used in your project. Run pip freeze > requirements.txt

  • Instead of `requirements.txt` I'm using Pipfile. Although I did try to run exactly as it is but with a `requirement.txt` file and no `Pipfile` and `Pipfile.lock`. No use. As for the `Procfile` being at the same folder as `manage.py`, I still get the `No module named 'django_project.wsgi'` error, but the log also shows something different: it gives me a `at=error code=H14 desc="No web processes running"` error. – Laila Campos May 13 '22 at 20:04
  • I tried running the command `heroku local web` to see if it's working locally and it tells me that it the `Procfile` is missing: `[WARN] ENOENT: no such file or directory, open 'Procfile' [FAIL] No Procfile and no package.json file found in Current Directory - See run-foreman.js --help` – Laila Campos May 13 '22 at 20:04

With Procfile at the root directory (that is, one level above manage.py), I've changed its content to the following:

web: gunicorn --pythonpath django_project django_project.wsgi --log-file -

As per this answer.

Here's my project structure now, just in case it wasn't clear where Procfile is located:

enter image description here

Now everything works as it should.

I'm marking this question as solved.
