SyntaxError: invalid syntax

[Abeautifulsnow]

Does django-celery support python3.7 or higher in the future?

The version now I used is python3.8 which causes some errors like syntax invalid with kombu.async because the async is a keyword from python3.7, so shall we support the newer python?

[auvipy]

please update celery to 4.4.6

please update celery to 4.4.6

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
django-celery 3.3.1 requires celery<4.0,>=3.1.15, but you have celery 4.4.6 which is incompatible.

But this version of celery is incompatible with django-celery 3.3.1...

[auvipy]

this package is only for celery 3.x for celery 4.x and 5.x try django-celery-beat & django celery result

[Alegorreta-mex]

I had the same problem, but for requeriments of the project I had to stay in django 2.1 and celery 3. I was able to run changing in the library of kombu the carpet call async to asynchronous (this change was introduced in the change in version 4.2.0) also in the library celery I search all the call to async module and change with asynchronous. it pass all my test in my applicaction but i dont sure if that break the code in some other parts, that i dont use.

Hope that this help you

my env:
python3.7
Django==2.1
celery==3.1.26.post2
django-celery==3.3.1
kombu==3.0.37

[auvipy]

please upgrade celery to 4.4/5.1

[auvipy]

for this package to work with python 3.7+ we need to release 2 new version of kombu and celery, which have the unrelesed supported code in specific 3.x branch
