Heroku error: bash: web:: command not found

Today my Heroku website was working fine but then I had to make lots of changes to the file and I definitely did something to it because now it doesn’t work anymore. I don’t know what could’ve changed the configuration.

Here is my Procfile:

web: python manage.py collectstatic --no-input; web: gunicorn --pythonpath ghiblimovs mysite.wsgi --log-file 

Here are my settings:

import os
import dj_database_url

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

This is the error I get when I push to Heroku:

Any help would be useful!

Your Procfile is broken:

web: python manage.py collectstatic --no-input; web: gunicorn --pythonpath ghiblimovs mysite.wsgi --log-file 

You're cramming two web process definitions into one line.

If you really want to chain things there, use &&:

web: python manage.py collectstatic --no-input && gunicorn --pythonpath ghiblimovs mysite.wsgi --log-file -

But Heroku runs collectstatic for Django applications by default. You don't need to put that in the Procfile. Something like this should do:

web: gunicorn --pythonpath ghiblimovs mysite.wsgi --log-file -

Note that you were also missing the - argument to --log-file. I've added it here.

Correct answer by Chris on December 29, 2020

web: gunicorn --pythonpath ghiblimovs mysite.wsgi --log-file

Answer gunicorn: pip install gunicorn

In your Procfile(letter p should spell Capital letter) in Procfile type code: web: gunicorn mysite.wsgi The app creash is cause of bad header request rest the heroku logs history setting folling you commit message.
