我正在尝试使用django + celery + rabbitmq + flower，但是在我使用pip3下载了flower之后：

在我的虚拟环境中，当我尝试使用

 celery -A myshop flower

在运行celery和rabbitmq时，我得到了这个错误：

Error: No such command 'flower'.

Did you mean one of these?
    worker

我已经在同一个目录中这样做了：

/home/denys/env2/myshop/myshop

end当我使用celery --help时，没有flower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.

  purge    Erase all messages from all known task queues.

我还试着使用：

celery flower -A myshop

我应该改变什么？谢谢)

Answer 1

看起来像10/1/20的最新版本的flower doesn't yet support celery v5.0.0。

正如Артур提到的，下降到4.4.7应该可以解决这个问题。

Answer 2

使用celery 4.4.7版本的mb就可以解决这个问题！

Answer 3

试试这个：

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

你可以通过address连接到你的rabbit server (in case it is not on local)的IP地址。

如果在执行pip freeze时会列出flower，也可以试一试。
