I’m trying to deploy a Python project using Django on Heroku. deploy is fine, but when trying to make Heroku run python Manage.py migrate the following error occurs.

This is my configs.py file

# Configuração da base de dados

# Caso seja deixado vazio o default será: 'sqlite:////...djangosige/db.sqlite3'
DEFAULT_DATABASE_URL = 'postgres://meuuser:minhasenhadbc@localhost/nomebd'

# Configurações do servidor de email

# Endereço de email padrão utilizado

DEFAULT_FROM_EMAIL = '[email protected]'

EMAIL_HOST = 'smtp.gmail.com'  # Gmail

# Usuário do email padrão
EMAIL_HOST_USER = 'meuuser'

# Senha do email padrão
EMAIL_HOST_PASSWORD = 'minhasenha'

#Verificar a port utilizada pelo serviço de email
EMAIL_PORT = 587

EMAIL_USE_TLS = True

My Settings.py

DEBUG = config('DEBUG', default=False, cast=bool)

if not DEFAULT_DATABASE_URL:
    DEFAULT_DATABASE_URL = 'sqlite:///' + os.path.join(APP_ROOT, 'db.sqlite3')

DATABASES = {
    'default': config('DATABASE_URL', default=DEFAULT_DATABASE_URL, cast=dburl),
}


# Application definition

INSTALLED_APPS = [

    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

Can anyone help me with this mistake? Thanks in advance

See the end of the error message:

EMAIL_PORT, EMAIL_USE_TLS ModuleNotFoundError: 
      No module named 'mjsolutions.configs.configs'

That is, Voce is calling a module that, although probably installed in its local environment (if it would not work), is not installed in Heroku, to work in Heroku all the packages needed to run in production have to be in the file called requirements.txt, a quick way to make sure you have everything in this file is with the command:

pip freeze > requirements.txt

Care:
If you use the command pip freeze > requirements.txt to generate requirements.txt revise this file at the end, as locally vc may have packages that are not needed by the project, such as debug packages, and especially if you are not isolating environments with some kind of venvs manager. If applicable, remove the unnecessary packets to run on Heroku.

Example of a file requirements.txt:
