Question

我在开始芹菜时遇到导入错误。这很令人困惑，因为这在几天前就已经开始了，git显示没有任何改变。我认为celery对导入目录的启发式方法与我的拆分设置结构相冲突，也许我的路径/ env与invokation工作时的路径/ env不同？我应该如何调整我的invokation或环境来帮助celery加载所有下游导入？这是Celery 3.1.7和Django 1.6。

我的邀请：

celery worker --app=proj.proj

错误：

ImportError: Could not import settings 'proj.settings.local' (Is it on sys.path?): No module named settings.local

我的项目如下：

proj <git root>
└──proj <project root>
   └── manage.py
   └── proj <project app>
       └── celery_app.py
       └── settings
           └── local.py

我的env vars是：

DJANGO_SETTINGS_MODULE=proj.settings.local
DJANGO_PROJECT_DIR=/home/ben/Projects/proj/proj/proj

编辑：我正在使用virtualenv，所以启动时我的$ PATH看起来像

PATH=/home/ben/.virtualenvs/proj/bin:
/usr/local/heroku/bin:/usr/lib/lightdm/lightdm:
/usr/local/sbin:/usr/local/bin:
/usr/sbin:
/usr/bin:
/sbin:
/bin:
/usr/games:
/usr/local/games

Answer 1

我的virtualenv以某种方式被腐蚀了。一个新的virtualenv具有相同的env vars和已安装的软件。

Answer 2

你芹菜使用错误的工作目录，因此无法找到相对路径proj.settings.local

尝试将您的设置修改为DJANGO_PROJECT_DIR=/home/ben/Projects/proj/proj并查看其是否有效。
