是因为不小心在settings.py中TEMPLATES加了app注册, 将其注释掉即可

TEMPLATES = [
    {
        ‘BACKEND‘: ‘django.template.backends.django.DjangoTemplates‘,
        ‘DIRS‘: [os.path.join(BASE_DIR, ‘templates‘)]
        ,
        ‘APP_DIRS‘: True,
        ‘OPTIONS‘: {
            ‘context_processors‘: [
                ‘django.template.context_processors.debug‘,
                ‘django.template.context_processors.request‘,
                ‘django.contrib.auth.context_processors.auth‘,
                ‘django.contrib.messages.context_processors.messages‘,
                ‘press.apps.AppConfig‘,
            ],
        },
    },
]

django中TypeError: __init__() missing 1 required positional argument: 'app_module'
