我尝试从命令行启动 Celery 工作服务器:
celery -A tasks worker --loglevel=info
tasks.py 中的代码:
import os
os.environ[ 'DJANGO_SETTINGS_MODULE' ] = "proj.settings"
from celery import task
@task()
def add_photos_task( lad_id ):
...
我得到下一个错误:
Traceback (most recent call last):

有人知道为什么找不到“芹菜”属性吗?谢谢你的帮助。
操作系统是 Linux Debian 5。
编辑. 可能是线索。谁能解释我对函数的下一条评论(为什么我们必须确保它在当前目录中找到模块)?
# from celery/utils/imports.py
def import_from_cwd(module, imp=None, package=None):
"""Import module, but make sure it finds modules
located in the current directory.
Modules located in the current directory has
precedence over modules located in `sys.path`.
"""
if imp is None:
imp = importlib.import_module
with cwd_in_path():
return imp(module, package=package)
