ImportError:无法在包中从'django.conf.urls‘导入名称'url’
ImportError:无法在包中从'django.conf.urls‘导入名称'url’
提问于 2022-07-10 17:32:38
我有一个将django web应用程序从Django-3.2.14迁移到Django-4.0的项目。迁移之后，当我运行服务器时，就会得到控制台输出中所示的错误。当我跟踪更改时，它跟踪到django-compat包，django-background-tasks包正在调用该包。my_env是我的虚拟环境。
我们有最新版本的django-compat ( 1.0.15 )和django-background-tasks ( 1.2.5 )。
你能查一下这个吗？
提前谢谢你。

更新答复
遗憾的是，目前还没有支持django-background-tasks的版本。看起来，如果不迁移到任何其他包，您就无法升级到django 4.0，它将完成与django-background-tasks相同的工作。
旧答案
包background_task使用的是django-compat，新的django版本不支持它。
D:\New_Folder\github\myenv\lib\site-packages\background_task\models.py
from compat import StringIO据我在堆栈跟踪中所见，不需要再使用django-compat包了。background_task包应该直接从默认的io包中使用io。
您将需要background_task包的更新版本，它不再使用django-compat包。据我所见，在没有依赖项的情况下没有新版本。
