求助：Django项目出现ModuleNotFoundError: No module named 'rest_framework.router'

我是开发领域的新手，在Django项目中遇到错误：ModuleNotFoundError: No module named 'rest_framework.router'。我已尝试将django、djangorestframework等所有相关包更新至最新版本，查阅官方文档也未找到解决思路，该问题已困扰我超过一天。以下是报错堆栈、我的urls.py配置及INSTALLED_APPS配置：

    from rest_framework.router import DefaultRouter
ModuleNotFoundError: No module named 'rest_framework.router'

我的urls.py配置 #

from django.urls import include, path
from product.views import ProductViewSet
from rest_framework import routers
from rest_framework.router import DefaultRouter

router = DefaultRouter()
router.register('', ProductViewSet, basename="ProductViewSet")

urlpatterns = [
    path('', include(router.urls)),
]

我的INSTALLED_APPS配置 #

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'rest_framework',
'product',
]

解决办法 #

问题出在导入路径的拼写错误：DefaultRouter所在的模块是rest_framework.routers（复数形式），不是rest_framework.router。你只需要修正导入语句即可，其他配置没有问题。

修正后的urls.py代码：

from django.urls import include, path
from product.views import ProductViewSet
from rest_framework.routers import DefaultRouter  # 改为复数routers

router = DefaultRouter()
router.register('', ProductViewSet, basename="ProductViewSet")

urlpatterns = [
    path('', include(router.urls)),
]
