今天用pip安装一些常用库,然后出现以下这段代码。

需要升级一下pip

WARNING: You are using pip version 20.3.1; however, version 21.3.1 is available.
You should consider upgrading via the 'c:\program files\python\python.exe -m pip install --upgrade pip' command

参考

阿里巴巴开源镜像站

首先切换使用国内阿里巴巴的pypi镜像源

a. 找到下列文件(windows目录:C:\Users\Administrator)

~/.pip/pip.conf

b. 在上述文件中添加或修改:

[global]
index-url = https://mirrors.aliyun.com/pypi/simple/

[install]
trusted-host=mirrors.aliyun.com

接着升级pip

cmd下输入:python -m pip install --upgrade pip

ok

接着就可以继续使用pip install xxxxx 安装库了
