Django新应用程序在开发人员中工作，但不在生产环境中工作（Apache服务器）

时间：2018-11-27 12:38:06

标签： python django apache mod-wsgi wsgi

我有一个django网站，可以在生产和开发中正常工作，最近我下载了django-tables2并进行了一些工作，在本地服务器上的开发没有问题。

但是，当将其放在生产服务器上时，转到URL时会出现错误500。

我是通过sudo pip install django-tables2

安装的

这是Apache的错误日志：

这是我的 INSTALLED_APPS 

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'coding',
    'django_tables2',
]

wsgi.py 

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'coding_platform.settings')

application = get_wsgi_application()

问题似乎来自wsgi.py，但我从未修改过此文件，我进行了很多研究，但没有发现错误，我的猜测是，下载额外的django时，还需要执行更多生产步骤包装，但我伤心的地方都没提到。

1 个答案:

答案 0 :(得分：0)

回溯中的关键是：

ModuleNotFoundError: No module named 'django_tables2'

您的新软件包未安装在生产虚拟环境中。祝你好运！
