目录
一、查看本机是否安装python
二、下载python的依赖包
三、下载安装包
四、解压到对应路径并安装
五、添加软链接并查看(类似于window电脑的快捷方式)
六、使用 python 3.9
一、查看本机是否安装python
[root@localhost ~]# python
二、下载python的依赖包
#切换至/usr/local/目录下
[root@localhost ~]# cd /usr/local/
[root@localhost ~]# cd /usr/local/
[root@localhost local]# ls
bin etc games include lib lib64 libexec sbin share src
#下载依赖包
[root@localhost local]# yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel
三、下载安装包
# 官方地址
wget https://www.python/ftp/python/3.9.0/Python-3.9.0.tgz
# 国内镜像
wget http://npm.taobao/mirrors/python/3.9.0/Python-3.9.0.tgz
[root@localhost local]# wget http://npm.taobao/mirrors/python/3.9.0/Python-3.9.0.tgz
四、解压到对应路径并安装
# 解压压缩包
tar -zxvf Python-3.9.0.tgz
# 进入文件夹
cd Python-3.9.0
# 配置安装位置
./configure prefix=/usr/local/python3
# 安装
make && make install
五、添加软链接并查看(类似于window电脑的快捷方式)
[root@localhost local]# ln -s /usr/local/python3/bin/python3.9 /usr/bin/python3.9
[root@localhost local]# ln -s /usr/local/python3/bin/pip3.9 /usr/bin/pip3.9
[root@localhost local]# python3.9 -V
Python 3.9.0
六、使用 python 3.9
[root@localhost local]# python3.9
Python 3.9.0 (default, Oct 6 2021, 11:22:19)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux
