Successfully installed flower-0.9.5

in my virtual env, when i tried to use

 celery -A myshop flower

with celery and rabbitmq running i got this error:

Error: No such command 'flower'.

Did you mean one of these?
    worker

I have done this in the same directory:

/home/denys/env2/myshop/myshop

end when i am using celery --help, there is no flower command:

  beat     Start the beat periodic task scheduler.
  call     Call a task by name.
  control  Workers remote control.

And also i tried to use:

The [1.0.0](https://github.com/mher/flower/issues/1029#issuecomment-873243638) release lets us use [celery>=5.0.5](https://github.com/mher/flower/blob/1.0/requirements/default.txt) — shad0w_wa1k3r, Apr 15 '22 at 17:46

Looks like the latest version of flower doesn't yet support celery v5.0.0 as of 10/1/20.

As Артур mentioned, dropping to 4.4.7 should resolve the issue.

Upgrading to Celery 5.0.0 breaks flower due to change in celery.bin.base module. #1029 https://github.com/mher/flower/issues/1029 – José Ibañez Oct 02 '20 at 19:06

Try this :

celery flower -A myshop --address=127.0.0.1 --port=5555

You can address to whatever is the IP of your rabbit server (in case it is not on local) .

Also try if you will get flower listed when you execute pip freeze .
