Clarification required django celery,celery and djangoceleryemail compatabilty versions to handle asynchronous tasks

[Dilipkumar Noone]

I am new to Django.

I am developing one django application which needs following packages to handle asynchronous tasks in the back ground.

1.djangocelery

2.djangocelery email.

App definitions in My settings.py file:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'crispy_forms',
    'djcelery',
    'gspapp',
    'djcelery_email',
    #'django_celery_results',
]

But when i install these packages in my virtual environment, I encountered with the below errors:

1.I have django-celery - 3.3.1 and celery 4.3.0 initially.

2.when i execute the celery worker command :celery -A gspaat worker --loglevel=info

i got the below error:

==========================================================

ModuleNotFoundError: No module named 'kombu.asynchronous'

==========================================================

As per the message posted in below link,i uninstalled celery version and installed latest celery version 4.3.0 .

But unfortunately i am facing with below error.

=====================================================================================================================

ERROR: django-celery 3.3.1 has requirement celery<4.0,>=3.1.15, but you'll have celery 4.3.0 which is incompatible.

Due to above error, i installed celery version :3.1.25 using pip install celery==3.1.25 but i got the below error 

ERROR: django-celery-email 2.0.2 has requirement celery>=4.0, but you'll have celery 3.1.25 which is incompatible.

=====================================================================================================================

So, please share the compatible version of djcelery , celery and djcelery_email.

Regards,

N.Dilip Kumar.

Hi,

You don't need to install anything but the celery package. Django celery and other variants are not supported anymore.

So all you need to do is install celery and follow the instructions here:

http://docs.celeryproject.org/en/latest/django/index.html

Best regards,

Andréas
