【问题描述】：

在我的 Django 项目market 中，我创建了一个名为main 的应用程序。在main 我创建了urls.py

main/urls.py:

from django.urls import path
import views
url_patterns = [
    path('home/', views.homepage, name='home'),

]

main/views.py:

from django.shortcuts import render, HttpResponse

# Create your views here.

def homepage(request):
    return HttpResponse("<h1> Hello World </h1>" )

market/urls.py:

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

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

但是当我尝试运行时：

Exception in thread django-main-thread:

    import views
ModuleNotFoundError: No module named 'views'

为什么不运行？

编辑：我还尝试用from market.main import views 替换main/urls.py 中的import views。没用。

【问题讨论】：

您的代码与错误消息不匹配。你的代码没有提到market.main，它只是说import views。
@MattDMo 那是通过尝试导入来查看它是否会改变任何东西。我把它修好了，所以它匹配。
from . import views

标签： python python-3.x django

【解决方案1】：

我发现我所做的有两个问题：

我没有正确导入views.py。我应该在main/urls.py 中使用from . import views 而不是import views。（感谢用户@bdbd）
在main/urls.py 我写的是url_patterns 而不是urlpatterns
