运行Django服务器时出现问题。继续获取以下错误：AttributeError:模块“Django.utils.termcolors”没有属性“get”

Question

我是Django的新手，这是我在Django的第一个项目。该项目运行正常，但我不确定现在发生了什么，因为在尝试使用命令运行服务器时，我不断遇到以下错误：

python3 manage.py runserver

以下是我得到的全部错误：

Traceback (most recent call last):

    format = color_settings.get(role, {})
AttributeError: module 'django.utils.termcolors' has no attribute 'get'

The above exception was the direct cause of the following exception:

During handling of the above exception, another exception occurred:
