Django 无法运行 manage.py runserver 如何解决？

Question

我正在尝试运行 manage.py 服务器，但遇到了一些错误！ 我只是想在网络上打印 hello 但它不起作用

(venv) ubuntu@node:~/PycharmProjects/Oin$ python manage.py runserver
Performing system checks...

    Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x7fd985430158>
    Traceback (most recent call last):

        iter(patterns)
    TypeError: 'module' object is not iterable

    During handling of the above exception, another exception occurred:

如果您想要任何 .py 文件，请随时询问谢谢！ 我的项目目录： https : //github.com/shreekantbatale2/Oinn

Answer 1

在您的仓库中
进行以下更改：
在openin / urls.py文件中：
您urlpatterns拼写错误（您对urlPatterns进行了编码）
在文件Oin / urls.py中
path('^$', include('openin.urls')),
至
path('', include('openin.urls')),

Answer 2

看起来您需要在urls.py文件中使用以下两个选项之一：

from django.urls import path

from . import views

urlpatterns = [
    path('', views.index, name='home')
]

或者，如果您使用的是url分配器， 则更可能使用urls.py文件中的内容 ：

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^', views.index, name='home')
]

包装器 fn(*args, **kwargs) 文件“C:\\Users\\91639\\AppData\\Local\\Programs\\Python\\Python39\\lib\\site-packages\\django\\core\\management\\commands\\runserver.py”，第 118 行, 在 inner_run self.check(display_num_errors=True) 文件“C:\\Users\\91639\\AppData\\Local\\Programs\\Python\\Python39\\lib\\site-packages\\django\\core\\management\\base.py”，第 419 行，在 check all_issues = checks.run_checks( File "C:\\Users\\91639\\AppData\\Local\\Programs\\Python\\Python39\\lib\\site-packages\\django\\core\\checks\\registry.py"，第 76 行，在 run_checks new_errors = check(app_configs=app_configs, databases=databases) 文件“C:\\Users\\91639\\AppData\\Local\\Programs\\Python\\Python39\\lib\\site-packages\\django\\core\\checks\\urls.py”，第 40 行，在 check_url_namespaces_unique all_namespaces = _load_all_namespaces(resolver) 文件“C:\\Users\\91639\\AppData\\Local\\Programs\\Python\\Python39\\lib\\site-packages\\django\\core\\checks\\urls.py”中，第 67 行，在 _load_all_namespaces 命名空间中.extend(_load_all_namespaces(pattern, current)) 文件“C:\\Users\\91639\\AppData\\Local \\Programs\\Python\\Python39\\lib\\site-packages\\django\\core\\checks\\urls.py”，第 57 行，在 _load_all_namespaces url_patterns = getattr(resolver, 'url_patterns', []) 文件“C:\\Users\\91639 \\AppData\\Local\\Programs\\Python\\Python39\\lib\\site-packages\\django\\utils\\functional.py”，第 48 行，在get res = instance. dict [self.name] = self.func(instance) File "C:\\Users\\91639\\AppData\\Local\\Programs\\Python\\Python39\\lib\\site-packages\\django\\urls\\resolvers.py"，第 607 行，在 url_patterns 中从 e django.core.exceptions.ImproperlyConfigured 中引发 ImproperlyConfigured(msg.format(name=self.urlconf_name))：包含的 URLconf '<module 'hello.urls' from 'C:\\Users\\91639\\squadmate\\hello\\ urls.py'>' 中似乎没有任何模式。 如果您在文件中看到有效模式，则问题可能是由循环导入引起的。
