通过终端命令来创建新的 app 时报错

执行命令: python manage.py startapp mysite04

具体报错内容如下:

python 复制代码

Traceback (most recent call last):

ModuleNotFoundError: No module named 'mysite04'

原因: settings.py 文件中 INSTALLED_APPS 中有的 mysite04没有声明

python 复制代码

INSTALLED_APPS = [
  	"mysite04",
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
]
