Ubuntu16.04默認安裝了Python2.7和3.5

請注意，系統自帶的python千萬不能卸載！

輸入命令python

按Ctrl+D退出python命令行

輸入命令sudo add-apt-repository ppa:jonathonf/python-3.6

按Enter確認

輸入命令sudo apt-get update

輸入命令sudo apt-get install python3.6

按Y確認

 

調整Python3的優先級，使得3.6優先級較高

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

更改默認值，python默認爲Python2，如今修改成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

 

此時再輸入命令python

能夠看到此時已是Python3.6了

添加by xiaou：

若是須要py3.6的開發環境：(由於須要python3.6m的so和/usr/include/python3.6m裏的頭文件)：

sudo apt-get install python3.6-dev
