Heroku app: ModuleNotFoundError: No module named ‘pwa’

I am trying to deploy my app to heroku and I keep getting this error even though when I run locally it works perfectly fine. I have added django-pwa==1.0.10 to my requirments.txt file also so that heroku installs the package. Here are my installed apps in settings.py:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'pwa',
    # 'embed_video',
    'whitenoise.runserver_nostatic',
    'courses.apps.CoursesConfig',
    'accounts.apps.AccountsConfig',
    'announcements.apps.AnnouncementsConfig',
    'students.apps.StudentsConfig',
    'home.apps.HomeConfig',
    'event_calendar.apps.EventCalendarConfig',
]

Here is my directory

Not really sure what to do as I am not very experienced with heroku.

Answer

By default Heroku will try to install every app from your requirements.txt, so before going any further make sure of the following:

• You have run pip freeze > requirements.txtto reflect the change
• Your path for the Procfile is correct

If it does not work after the troubleshooting, add your log from heroku to your first question, your procfile and requirements.txt.
