from celery_tasks.sms.tasks import send_sms_code
ImportError: No module named 'celery_tasks'
No module named 'celery_tasks'，大概意思就是没有这个模块，为什么会报这个错误呢，想想，是否创建了这个模块，在想路径有没有问题？
其实就是导包路径的问题，既然提示找不到这个模块，那就是这个模块的路径找不到，最简单的解决办法就是在配置文件setting中找到导包路径
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))找到这一行，在下面输出 print(sys.path) 查看以下，你的导包路径是否在这里面，如果没有就加上celery_tasks的路径
我的celery_tasks的文件在
/home/python/Desktop/project 下面，所以我就在setting.py中添加了两行代码
import sys
CELERY_DIR = '/home/python/Desktop/project'
sys.path.insert(0,CELERY_DIR)
