Ubuntu16.04怎样安装Python3.6
转自: https://www.cnblogs.com/yjlch1016/p/8641910.html
Ubuntu16.04默认安装了Python2.7和3.5
请注意,系统自带的python千万不能卸载!
输入命令python
按Ctrl+D退出python命令行
输入命令sudo add-apt-repository ppa:jonathonf/python-3.6
按Enter确认
输入命令sudo apt-get update
输入命令sudo apt-get install python3.6
按Y确认
调整Python3的优先级,使得3.6优先级较高
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2
更改默认值,python默认为Python2,现在修改为Python3
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150
此时再输入命令python
可以看到此时已经是Python3.6了
添加by xiaou:
如果需要py3.6的开发环境:(因为需要python3.6m的so和/usr/include/python3.6m里的头文件):
sudo apt-get install python3.6-dev
