ModuleNotFoundError:没有名为“注册”的模块
我的 Settings.py、Urls.py 和 HTML 模板文件的屏幕截图附在下面:

来自 docs :

Prior to 3.x, django-registration installed a Python module named registration. To avoid silent incompatibilities, and to conform to more recent best practices, django-registration 3.x now installs a module named django_registration. Attempts to import from the registration module will immediately fail with ImportError.
