Python pip版本升级

pip版本升级命令:

　　python -m pip install --upgrade pip

如果报错代码如下:

(venv) C:\Users\ssdy\PycharmProjects\untitled>python -m pip install --upgrade pip

You are using pip version 10.0.1, however version 19.1.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

如此报错,可能是网速不行,下载超时,关掉你的网页以及部分软件,重新执行命令
