[英]ModuleNotFoundError: No module named 'social.models' when running celery worker
[英]No module named app when running celery worker -A app in EB .ebextensions
我將如何在Elastic Beanstalk celeryd
和redis設置為守護程序,具體如何使用AWS Elastic Beanstalk運行工作程序? 。
我想我快到了。 Redis正在彈性緩存上運行並且可以訪問。
但是用於設置celeryd
的.ebextesions
文件在特定行上失敗。 請參閱.ebextensions
進一步在.ebextensions
運行的整個腳本。
行: command=/opt/python/run/venv/bin/celery worker -A myappname --loglevel=INFO
。
我嘗試了命令的一些不同變體。
嘗試:
command=/opt/python/run/venv/bin/celery worker -A /opt/python/current/app/app.py --loglevel=INFO
(我的app.py目錄)
command=/opt/python/run/venv/bin/celery worker -A app.py --loglevel=INFO
(我的app.py的名稱)
command=/opt/python/run/venv/bin/celery worker -A app --loglevel=INFO
(名稱不帶擴展名)
command=/opt/python/run/venv/bin/celery worker -A flask-celery-01 --loglevel=INFO
(彈性beantalk中的應用程序名稱)
command=/opt/python/run/venv/bin/celery worker -A myappname --loglevel=INFO

這可能是因為我的flask應用程序app.py
分為模塊(所有內容都在app.py
)。 而且我還沒有像某些教程中所看到的那樣“安裝”該應用程序。 只需與EB一起部署,Web UI即可工作。
Flask和AWS對我來說都是新手。 並很樂意將其投入生產。

app.run() # debug=True
您需要像下面一樣使用它
celery worker -A app:celery --loglevel=info
ABC:D
語法意味着導入ABC
並使用相同的D
