在我的虚拟环境中，当我尝试使用

 celery -A myshop flower

芹菜和rabbitmq 运行我得到这个错误：

Error: No such command 'flower'.

Did you mean one of these?
    worker

我在同一目录中完成了此操作：

/home/denys/env2/myshop/myshop

当我使用 celery --help 时结束，没有花命令：

Commands:
  amqp     AMQP Administration Shell.
  beat     Start the beat periodic task scheduler.
  call     Call a task by name.
  control  Workers remote control.
  events   Event-stream utilities.
  graph    The ``celery graph`` command.
  inspect  Inspect the worker at runtime.
  list     Get info from broker.
  logtool  The ``celery logtool`` command.
  migrate  Migrate tasks from one broker to another.
  multi    Start multiple worker instances.
  purge    Erase all messages from all known task queues.
  report   Shows information useful to include in bug-reports.
  result   Print the return value for a given task id.
  shell    Start shell session with convenient access to celery symbols.
  status   Show list of workers that are online.
  upgrade  Perform upgrade between versions.

我也尝试使用：

celery flower -A myshop

我应该改变什么？谢谢）

Answer 1

截至 20 年 1 月 10 日，最新版本flower 似乎还不支持 celery v5.0.0。

作为 ？？？？？提到，降到 4.4.7 应该可以解决这个问题。
