Django 新应用程序在开发中工作但不在生产中（Apache 服务器）

Question

我有一个在生产和开发中正常工作的 django 网站，最近我下载了 django-tables2 并使用它在本地服务器上进行开发没有问题。

然而，当把它放在我的生产服务器上时，它在转到 url.

时给我错误 500

我通过 sudo pip install django-tables2

安装了它

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，但我从未修改过这个文件，我做了很多研究但没有发现问题所在，我的猜测是生产需要额外的步骤下载额外的 django 包时，但在我读到的任何地方都没有提到它。

Answer 1

回溯中的关键行是：

ModuleNotFoundError: No module named 'django_tables2'

您的新软件包未安装在您的生产 virtualenv 中。祝你好运！
