Django - AttributeError：“模块”对象没有属性“TEMPLATE_CONTEXT_PROCESSORS”

Question

我有一个崩溃的生产 python 应用程序。尝试打开网站时，我得到一个 502 bad gateway。尝试使用 python manage.py restart 重新启动 django 应用程序后，出现以下错误。

 Traceback (most recent call last):


File "manage.py", line 23, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/lib64/python2.7/site-packages/django/core/management/__init__.py", line 367, in execute_from_command_line
    utility.execute()

    TEMPLATE_CONTEXT_PROCESSORS = global_settings.TEMPLATE_CONTEXT_PROCESSORS + (
AttributeError: 'module' object has no attribute 'TEMPLATE_CONTEXT_PROCESSORS'

我没有更改代码或配置上的任何内容，我不知道为什么会这样。我检查了类似的错误，但没有解决这个问题。

谢谢

编辑：

base.py

...
from django.conf import global_settings
TEMPLATE_CONTEXT_PROCESSORS = global_settings.TEMPLATE_CONTEXT_PROCESSORS + (
    'django.core.context_processors.request',
    'home.context_processors.system_config',)
...

global_settings = https://github.com/django/django/blob/master/django/conf/global_settings.py

编辑 2：

我删除了对 global_settings.TEMPLATE_CONTEXT_PROCESSORS 的调用。之后我必须安装许多从 base.py 调用的模块，这很奇怪，因为网站运行良好，我不知道这些模块是怎么丢失的...... 安装完所有模块后，我达到了无法为 postgres 安装模块的地步

我非常感谢您的帮助，因为该网站正在运行，现在已关闭超过 12 小时。

您似乎没有在与以前相同的虚拟环境中重新启动 Django，因为 Django 版本似乎已更改，并且您收到 psycopg2 的导入错误。

听起来您可能在生产中使用runserver。你不应该这样做，这是不安全的。 Django docs 描述了如何正确部署 Django。
