Linux下安装python3

Posted 2020-12-02 90500042陈

 

 

 

系统版本：

[[email protected] scripts]# cat /etc/redhat-release
CentOS release 6.9 (Final)

 

之前的python版本：

[[email protected] scripts]# python
Python 2.6.6 (r266:84292, Aug 18 2016, 15:13:37)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2

 

因为现在推广Python3 因而进行升级  保留原来的版本
