Question

我尝试使用 postgre DB在Apache（使用mod_wsgi）上启动Django（1.10.5）时出现500错误。安装依赖项是django和。的 psycopg2 即可。它们安装在 Python 3.6 虚拟环境中。

提示：当我尝试通过＆＃34; python manage.py runserver 0.0.0.0:8000"来启动虚拟环境时，一切正常。但是当我尝试在apache上访问：80端口时，/ var / log / httpd / error_log中列出了以下错误

wsgi.py的内容：

import os
import time
import traceback
import signal
import sys
from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'djangotest.settings'

try:
    application = get_wsgi_application()
    print("WSGI without exception")
except Exception:
    print("handling WSGI exception")
    # Error loading applications
    if 'mod_wsgi' in sys.modules:
        traceback.print_exc()
        os.kill(os.getpid(), signal.SIGINT)
        time.sleep(2.5)

尽管psycopg2成功地安装在venv上并且工作正常，但是当尝试达到时，它会引发错误：80通过apache＆amp; mod_wsgi的。

谢谢。
