在生產服務器上部署期間，我在 django 應用程序中收到 500 內部服務器錯誤 ModuleNotFoundError: No module named 'main' (wsgi:error)

Question

我想使用 mod_wsgi 為我的項目提供服務。 當我運行開發服務器時，它已啟動，但在生產服務器上出現錯誤。我的操作系統是 RedHat 並使用配置了 python3-mod_wsgi 的 httpd(apache) 虛擬主機。

這是我的錯誤

這是我的項目 wsgi.py 文件

 import os import sys #from django.conf import settings from django.core.wsgi import get_wsgi_application #sys.path.append('/var/www/public_html/main/') os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'main.settings') application = get_wsgi_application()

我將我的 wsgi.py 文件更改為此現在它正在工作

 """ WSGI config for main project. It exposes the WSGI callable as a module-level variable named ``application``. For more information on this file, see https://docs.djangoproject.com/en/3.0/howto/deployment/wsgi/ """ import os import sys from django.core.wsgi import get_wsgi_application sys.path.append('/var/www/public_html/') os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'main.settings') application = get_wsgi_application()
