Django urls.py: RecursionError: 调用 Python 对象时超出最大递归深度

Question

我想在我的应用程序中创建一个指向我的 urls.py 的 url，但它每次都会给我一个 RecursionError。 这是我的代码：

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('shop/', include('ptr.urls'))
]

如果你需要完整的追溯，这里是：
