【问题描述】：

我是 Django 新手，我正在尝试使用模型和迁移，在我尝试执行命令之前一切正常：python manage.py makemigrations 它引发错误的地方：

TypeError: 'module' 对象不可迭代

我尝试重新安装 Django 并在我的代码编辑器上创建一个新的 venv 并更改设置，基本上我可以在网上找到所有内容，但我遇到了这个错误（完整如下）。

Traceback (most recent call last):
  File "C:\Users\Emanuele\Desktop\Django_Env\lib\site-packages\django\urls\resolvers.py", line 591, in url_patterns
    iter(patterns)
TypeError: 'module' object is not iterable

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

【问题讨论】：

告诉我们flights.urls！

标签： python django

【解决方案1】：

在您的 flights 应用程序中，您必须创建一个名为 urls.py 的文件（如果存在）而不是添加新文件，然后您必须添加 urlpatterns在你的 urls.py

将此添加到您的 flights/urls.py

app_name="flights"

urlpatterns = [

]

【解决方案2】：

尝试使用python manage.py makemigrations（插入您的 Django 应用名称）

【解决方案3】：

再次检查你的拼写我有 urlpatters [] 而不是 urlpatterns = [] 并给出了同样的错误。
