Redis 计划错误：无法'；t apply scheduled task downloader:参数必须是int或具有fileno（）方法

我在django应用程序中添加了django芹菜和kombu.transport.django

settings.py： 芹菜 芹菜管理器配置： 当使用django芹菜接口（本应下载一些文件）计划任务时，会引发以下错误：

我不知道这些错误是从哪里来的

如有任何建议，将不胜感激

更新1： 我使用django芹菜管理界面来安排任务，任务在已安装的应用程序中注册的应用程序中定义如下：

@shared_task
def downloader():
    # execute static/shell_scripts/feed_downloader.sh
    import subprocess
    PROJECT_PATH = os.path.dirname(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))
    subprocess.call(PROJECT_PATH+"/static/shell_scripts/feed_downloader.sh", shell=True)

feed_downloader.sh文件调用一个django管理命令，如果我独立执行，该命令可以正常工作，如：

python manage.py feed_downloader

如果我在第85行之前添加一个print语句来检查文件中的

fd

参数

/home/vagrant/.virtualenvs/project/local/lib/python2.7/site-packages/kombu/utils/eventio.py

然后打印以下消息：

see this <socket._socketobject object at 0x131b750>
see this None
see this <socket._socketobject object at 0x131bc90>
see this None

看看这个
看到这个了吗

如何创建芹菜任务？看起来您正在传递无法通过代理发送的参数中的对象。@daniula有时会执行计划任务，并且在大多数情况下会抛出上述错误……我还将工作人员的数量从1个增加到4个，工作了一两次，然后又开始出错。它与worker或redis有关吗？此外，我还添加了

BROKER\u TRANSPORT\u OPTIONS={'visibility\u timeout'：3600}芹菜\u ACKS\u LATE=True

，但情况并没有改善。我发现，若计划时间大约为2分钟或更短，则下载程序任务会成功执行，但若超过该时间，则会抛出上述参数错误。这意味着redis正在使作业队列中的作业过期？？

python manage.py feed_downloader

/home/vagrant/.virtualenvs/project/local/lib/python2.7/site-packages/kombu/utils/eventio.py

see this <socket._socketobject object at 0x131b750>
