python - Django Wsgi ModuleNotFoundError : No module named 'project_name'

Question

我正在尝试使用 WSGI 和 NGINX 部署一个 Django 项目。问题是在启动时，日志显示模块丢失错误
通过 service uwsgi restart 启动时命令，日志/var/log/uwsgi/app/django.log中出现错误:

因为这可能是什么？如何解决？

根据此答案 https://stackoverflow.com/a/42981216/10905324，您的项目文件夹可能需要添加到 wsgi.py 中的路径

import os
import sys
sys.path.append('/home/django_projects/MyProject')
sys.path.append('/home/django_projects/MyProject/project_name')

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project_name.settings.production')

application = get_wsgi_application()
