Django AttributeError:“module”对象没有属性“TEMPLATE_CONTEXT_PROCESSORS”

Question

我有一个python应用程序在生产中崩溃了。当我试图打开网站时，我得到了一个502坏网关。在尝试使用python manage.py restart重新启动django应用程序后，我得到了以下错误。在

 Traceback (most recent call last):


File "manage.py", line 23, in <module>

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

我没有更改代码和配置，我不知道为什么会这样。我检查过类似的错误，但他们没有解决这个问题。在

谢谢

编辑：

在基准.py在

^{pr2}$

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

编辑2：

我取消了全球电话_settings.TEMPLATE_CONTEXT_处理器. 之后，我必须安装许多从基准.py，这很奇怪，因为网站运行得很好，我不知道为什么那些模块丢失了。。。 在安装了所有的模块之后，我可以达到无法安装postgres模块的程度

我真的很感谢帮助，因为该网站正在生产，现在关闭超过12小时。在

看起来您没有像以前一样在同一个虚拟环境中重新启动Django，因为Django的版本似乎已经更改，并且您将收到psycopg2的导入错误。在

听起来您可能正在生产中使用runserver。你不应该这样做，这是不安全的。{a1}描述了如何正确地部署Django。在
