在 python3 manage.py 运行服务器中运行我的 django 项目时，我收到此错误 ModuleNotFoundError: No module named 'pip._vendor.urllib3.connection'

问题描述

运行 python3 manage.py runserver 后，出现以下错误：

回溯（最近一次调用最后一次）： 文件“manage.py”，第 11 行，在主目录中 从 django.core.management 导入 execute_from_command_line 文件“/Users/luiseduardo/Practice/nova/nova_venv/lib/python3.8/site-packages/django/core/management/init.py”，第 12 行，在 从 django.conf 导入设置 导入错误：无法从“django.conf”（未知位置）导入名称“设置”

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

Traceback (most recent call last):
  File "manage.py",line 22,in <module>
    main()
  File "manage.py",line 13,in main
    raise ImportError(

我使用的是 mac 并且我确实激活了我的 virtualenv。

解决方法

我遇到了同样的问题，这为我解决了：pip install --upgrade pip
