我在dev VM&ubuntu / trusty'下有一个项目。 我将 virtualenv 与以下软件包一起使用:
celery 3.1.23
eventlet 0.18.4
django 1.8.15
Python版本是3.4.3。
当我以这种方式开始一个芹菜工人时:
celery worker --loglevel=INFO -P eventlet -c 3 -Q default -E -n default.queue -l INFO
它正确启动,但所有任务都保留在' 待处理'状态。
当我以这种方式启动时(在' -A' 参数中使用项目名称):
celery worker -A meridian --loglevel=INFO -P eventlet -c 3 -Q default -E -n default.queue -l INFO
它发出错误:
(meridian)vagrant@vagrant-ubuntu-trusty-64:/vagrant/meridian/meridian$ celery worker -A meridian --loglevel=INFO -P eventlet -c 3 -Q default -E -n default.queue -l INFO
Traceback (most recent call last):

found = sym.app

During handling of the above exception, another exception occurred:

有人知道如何解决这个问题吗?

您的项目(应用程序)似乎无法导入。
您的选择:
pip install /project/directory
进行安装。这将在virtualenv/lib/python-version/site-packages/
中创建文件的 copy 。通过这本书,但很少使用的方法。pip install -e /project/directory
还需要setup.py,将项目符号链接到site-packages,因此它是每个virtualenv的一次性操作。广泛用于包开发人员。sys.path
。例:
import sys
sys.path.append('/project/directory')
PYTHONPATH
环境变量处理导入目录。通常的平台相关PATH
规则适用(条目由:
分隔,但Windows上为;
。这种方式非常适合部署。 shell中的示例:
export PYTHONPATH=/project/directory
exec /virtualenv/bin/celery worker ...

我在这里找到了解决方案:
http://docs.celeryproject.org/en/latest/django/first-steps-with-django.html
我唯一需要做的就是将一个文件 celery.py 添加到项目的根目录中,然后添加几行到 init.py 放在同一目录中。请参阅上面的文档。
