PIP升级+安装Django命令[WARNING: Retrying (Retry(total=4, connect=None...]

升级：

>pip install -U Django

安装：

>pip install Django

如果发现超时错误内容：（WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError...）

可以尝试加上镜像源地址再次更新:
>pip install -i https://pypi.tuna.tsinghua.edu.cn/simple django
