1. window python 环境安装

pip –version pip 21.1.3 from d:\local\python3\lib\site-packages\pip (python 3.9)

where python D:\local\python3\python.exe

d:\local\python3\python.exe -m pip install –upgrade pip

• pip show 包名来查看包的相关信息

  pip show selenium Name: selenium Version: 3.141.0 License: Apache 2.0 Location: d:\local\python3\lib\site-packages 【第三方包的按照路径】

2. centos7升级python3

wget https://www.python.org/ftp/python/3.9.7/Python-3.9.7.tgz tar xzvf Python-3.9.7.tgz mkdir /usr/local/python3/ ./configure –prefix=/usr/local/python3 make install mv /usr/bin/python /usr/bin/python.bak mv /usr/bin/pip /usr/bin/pip.bak ln -s /usr/local/python3/bin/python3.8 /usr/bin/python ln -s /usr/local/python3/bin/pip3 /usr/bin/pip python -V vim /usr/bin/yum 把最顶部的#!/usr/bin/python改为：#!/usr/bin/python2.7
