1、申請雲主機，部署ubuntu主機，開放22埠
2、系統ubuntu16.04，系統自帶2個版本的python，乙個是python2.7，乙個是python3.5
安裝pip工具
sudo apt-get install python3-pip
安裝本地虛擬環境管理工具
sudo apt-get install python3-virtualenv
python2 --version #檢視python2安裝版本
python3 --version #檢視python3安裝版本
echo alias python=python3 >> ~/.bashrc
source ~/.bashrc
python --version 變成python3了
