ModuleNotFoundError: No module named 'restaurants'

Answer 1

您已经在您的 settings.py 中的 installed_apps 部分定义了一个名为 restaurant 的应用程序，但是没有找到它的模块。

Answer 2

我有一个类似的问题。 当我检查 setting.py 时，我发现我忘记了一个逗号。 Seggust 去检查一下..

INSTALLED_APPS = [
'home' , #This One was Missed
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]

还要检查餐厅文件夹在哪里，它应该类似于：

project|
       |restaurant
       |project

不是：

project|           
       |project|
               |restaurant
