\[root@study ~\]\# cat /etc/redhat-release  
CentOS Linux release 7.7.1908 (Core)

\[root@study ~\]\# yum install gcc make zlib zlib-devel openssl openssl-devel libffi-devel bzip2-devel ncurses-devel gdbm-devel readline-devel xz-devel sqlite-devel tk-devel -y

\[root@study ~\]\# wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz //下载文件

\[root@study ~\]\# tar -zxvf Python-3.7.4.tgz //解压文件

\[root@study ~\]\# cd Python-3.7.4/ //进入Python-3.7.4解压目录

\[root@study ~\]\# ./configure prefix=/usr/local/python3 //这里安装在/usr/local/python3 目录下，有需要安装在其他地方的则修改目录为想要安装的位置

\[root@study ~\]\# make //编译

\[root@study ~\]\# make install //执行安装

\[root@study ~\]\# ln -s /usr/local/python3/bin/python3 /usr/bin/python3 //安装完成就配置软连接

\[root@study ~\]\# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3 //安装完成就配置软连接

最后一步验证

\[root@study ~\]\# python3 -V  
Python 3.7.4  
\[root@study ~\]\# pip3 -V  
pip 19.0.3 from /usr/local/python3/lib/python3.7/site-packages/pip (python 3.7)

返回了安装的版本信息则说明安装成功，接下来可以升级pip3

\[root@study ~\]\#pip3 install --upgrade pip
