芹菜錯誤「沒有這樣的運輸：AMQP」

Question

芹菜是工作的罰款，一天命令行工作人員未能與以下跟蹤啓動：

Traceback (most recent call last):

    raise KeyError('No such transport: %s' % (transport,)) 
KeyError: 'No such transport: amqp' 

通過代碼跟蹤顯示「AMQP」神祕失蹤從kombu.transport.TRANSPORT_ALIASES - 但那是我失去了蹤跡。

該問題似乎是由於升級到celery 3.0.7所致。對我來說，下面的解決了這個問題：

pip install kombu==2.4.0 

注：我似乎這似乎已經由海帶== 2.4.3每https://github.com/celery/kombu/commit/c3b7a0d885fef3a43b76af0881fee6b5d012923f
