如何解决错误：没有这样的命令“ flower”您是这些意思之一吗？工人

我正在尝试使用Django +芹菜+ Rabbitmq +花卉，但是在我使用pip3下载花卉之后：

在我的虚拟环境中，当我尝试使用

 celery -A myshop flower

运行芹菜和Rabbitmq时出现此错误：

Error: No such command 'flower'.

Did you mean one of these?
    worker

我已经在同一目录中完成了此操作

/home/denys/env2/myshop/myshop

当我使用芹菜--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.
  worker   Start worker instance.

我也尝试使用：

celery flower -A myshop

我应该改变什么？谢谢）

解决方法

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

如Артур所述，降至4.4.7应该可以解决问题。

,

使用celery 4.4.7版本mb将解决此问题！

尝试一下：

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

您可以address到rabbit server (in case it is not on local)的IP上。

还尝试执行flower时是否列出pip freeze。
