在这里我得到了错误。 我的urls.py文件：
from django.contrib import admin
from django.urls import path, include,re_path,url
from django.conf import settings
from django.conf.urls.static import static
from django.views.static import serve
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('shopping.urls')),
re_path(r'^media/(?P<path>.*)$', serve,{'document_root': settings.MEDIA_ROOT}),
re_path(r'^static/(?P<path>.*)$', serve,{'document_root': settings.STATIC_ROOT}),
]
和 settings.py
DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'
STATIC_URL= "/static/"
STATIC_ROOT = os.path.join(BASE_DIR,'staticfiles')
MEDIA_ROOT= os.path.join(BASE_DIR, "media")
MEDIA_URL="/media/"
url(…)函数[Django-doc]自django-4.0以来已被删除，取而代之的是re_path(…)函数[Django-doc]你可以在发行说明[Django-doc]中找到它。
因此，您应该从导入中删除url ，因此：
from django.urls import path, include, re_path # no url我强烈建议您在开发和生产中使用相同的 Django 版本，因为很可能许多其他功能将（最终成为）弃用，因此这使得在生产服务器上调试变得困难。
注意：您不应该使用 Django 的功能在生产中提供媒体文件或静态文件。
serve(…)函数[Django-doc]效率低下并且可能不安全。 Django 文档解释了如何通过Nginx 、 Apache和其他经过优化以提供静态内容的机制来提供媒体和静态文件。 特别是因为这些可以与缓存一起使用，并且会省略 Django 使用的许多逻辑。
