uwsgi 错误：请求设置 DEBUG，但未配置设置

Question

您好，我正在尝试在 Amazon EC2 上设置 nginx+uwsgi+django，参考本教程http://www.yaconiello.com/blog/setting-aws-ec2-instance-nginx-django-uwsgi-and-mysql/#sthash.g42ylQcA.MJX0ZbDz.dpbs ,

但是得到了低于uwsgi的错误，

错误日志：

/home/ubuntu/web/lightea.com/wsgi.py

import os, sys, site, django.core.handlers.wsgi

SITE_DIR = '/home/ubuntu/web/lightea.com/elderlytracking/django_test/'
site.addsitedir(SITE_DIR)
sys.path.append(SITE_DIR)

os.environ['DJANGO_SETTINGS_MODULE'] = 'django_test.settings'
application = django.core.handlers.wsgi.WSGIHandler()

setting.py 位于 /home/ubuntu/web/lightea.com/elderlytracking/django_test/django_test 文件夹中。

Answer 1

试试这个：

import os
import sys

sys.path.append('/home/ubuntu/web/lightea.com/elderlytracking/django_test')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "django_test.settings") # here django_test is a directory within django_test project 

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
