# 编译安装
$ ./configure
$ make
$ sudo make install
$ python3 --version
# 设置默认版本
$ alias python='/usr/local/bin/python3.6'
# 1. 激活SCL
$ sudo yum install centos-release-scl
# 2.安装python3
$ sudo yum install rh-python36
# 3.使用python3
$ python --version
Python 2.7.5
$ scl enable rh-python36 bash
$ python --version
Python 3.6.3
# 4. 安装开发工具
$ sudo yum groupinstall 'Development Tools'
注意:
此处设定python3版本,如果重新打开会话,会恢复默认的python2.7
设置默认
$ scl enable python36 <command>
$ scl enable python36 bash
$ mkdir myapp
$ cd myapp
$ scl enable rh-python36 bash
