celery-django找不到設置

Question

我有一個Django項目，它使用Celery來運行異步任務。我正在Windows XP機器上進行開發。

開始我的Django的服務器（python manage.py runserver 80）工作正常，但嘗試啓動芹菜守護進程（python manage.py celeryd start）失敗，出現以下錯誤：

導入錯誤：無法導入設置「src.settings」（上是否sys.path？是否有語法錯誤？）：沒有名爲src.settings的模塊

sys.path包含'C：\ development \ SpaceCorps \ src'，所以我不確定它爲什麼找不到這個模塊。

下面是從啓動守護進程輸出全：

ImportError: Could not import settings 'src.settings' (Is it on sys.path? Does it have syntax errors?): No module named src.settings 

Answer 1

顯然這是running Celery on Windows的問題。使用- 設置變元ala python manage.py celeryd start --settings=settings做了訣竅。

Answer 2

sys.path中必須包括 'C：\研發\ SpaceCorps' 而不是 'C：\研發\ SpaceCorps \ src' 中， 因爲他正在尋找src.settings，而不僅僅是設置。
