django.core.exceptions.ImproperlyConfigured：無法加載 WSGI 應用程序“netfacer.wsgi.application”； 導入模塊時出錯

Question

我只是 django 的初學者。 我嘗試按照此鏈接創建子域。 當我運行我的項目時，它顯示以下錯誤

django.core.exceptions.ImproperlyConfigured：無法加載 WSGI 應用程序“netfacer.wsgi.application”； 導入模塊時出錯。

我的設置.py

上面鏈接中的文檔也讓我感到困惑

Answer 1

通常你必須在你的設置模塊中設置WSGI_APPLICATION變量，根據代碼netfacer.wsgi.application ，包含wsgi.py包被命名為netfacer 。 可能還有以下問題：

1. 沒有名為netfacer包 - 檢查您是否已重命名設置包
2. netfacer包位於您的<project_root>目錄中，檢查<project_root>目錄是否是PYTHONPATH環境變量的一部分

Answer 2

添加到您的 settings.py
中間件=[
'whitenoise.middleware.WhiteNoiseMiddleware',
]
wsgi.py
import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'your-project-Name.settings')

application = get_wsgi_application()

確保您的wsgi.py不低於上述配置

檢查並刪除

從 whitenoise.django 導入 DjangoWhiteNoise
應用程序 = DjangoWhiteNoise（應用程序）
