Heroku: My Django app is giving Application Error H14: "No Web Processes Running"

Question

According to the Heroku site when I get error H14 "No Web Processes Running" it's because I need to scale up dynos by:

heroku ps:scale web=1

However, when I do that I get the following error:

Scaling web processes... failed
 !    No such type as web

Does anyone know how to fix this? I want to get my site back up!

When I run heroku ps I see nothing.

UPDATE: It's not detecting my Procfile. I don't have a Procfile explicitly and didn't use one before... is it absolutely necessary?

Answer 1

I ran into this recently as well, my web was working fine without any Procfile, until recently... My fix was simply to add a Procfile as follows:

web: python manage.py runserver 0.0.0.0:$PORT --noreload

Then push to heroku.

Answer 2

For Heroku you need to add a Procfile.

1. add a Procfile on same level like your manage.py file. It should be in your root directory. Be sure that you create a Procfile not a Procfile.txt or else just Procfile

2. in your Procfile add:

   web: gunicorn projectname.wsgi

3. add in your requirements.txt gunicorn

   gunicorn==20.0.4

If you activate automatic deploy you can try it again. If you can remove the app, remove it and deploy it again.
