我正在尝试迁移到python3（3.6），并且从芹菜中遇到TypeError: an integer is required (got type NoneType)的问题，它引发了from celery import shared_task
QUEUE = 'ukrdc_importer'
@shared_task(queue=QUEUE)
def import_data(num1, num2):
return num1 + num2
@api.route('/import', methods=['POST'])
def import_():
res = import_data.delay(1, 1)
return Response(status=200)
。我设法将问题缩小到shared_task装饰器中的队列参数。这就是我所拥有的：
queue这是来自烧瓶应用程序。它在python2中工作得很好，如果我从shared_task调用中删除了127.0.0.1 - - [28/Sep/2018 14:17:11] "POST /import HTTP/1.1" 500 -

参数，它也可以工作，但是一旦添加，python3开始抛出所提到的异常，我不知道为什么... python2和3中的库版本相同。
