很多小伙伴在用pip安装插件时会出现如下错误提示，要怎么解决呢。

问题：WARNING: You are using pip version 22.0.4; however, version 22.1 is available.

You should consider upgrading via the 'C:\Users\ASUS\AppData\Local\Programs\Python\Python39\python.exe -m pip install --upgrade pip' command.

解决方法：

输入：python -m pip install --upgrade pip

执行。

如下载失败，可指定国内库。
python -m pip install --upgrade pip -i https://pypi.douban.com/simple
