Question

生成运行服务器导入错误。在这里，我甚至不在我的文件中的任何地方使用这种泛型类型。

那怎么会产生这个错误???

C:\Python34\python.exe manage.py runserver

ImportError: cannot import name 'generic'

Answer 1

您的tagging库不支持Django 2.0。如果您选中Django's git repo，则会在generic中看到不再有Django.contrib.contenttypes个模块。它在Django 1.9中删除了。降级到Django 1.8以使您的库工作，或者我建议使用不同的标记库，最好是一个足以维护至少支持Django 1.11的标记库。

Answer 2

我已经解决了这个错误。
在settings.py文件中，有INSTALLED_APPS。我删除了＆＃39;标记＆＃39; 从那解决我所有的错误。

希望这会有所帮助。
