Ubuntu 16.04 安装 python3.6

摘自：https://www.jianshu.com/p/e047f3685a64

1. Ubuntu16.04默认安装了python2.7和python3.5, 相关依赖已经安装，若没有则：

sudo apt-get install openssl
sudo apt-get install libssl-dev
sudo apt-get install libc6-dev gcc
sudo apt-get install -y make build-essential zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev 
wget curl llvm tk-dev

2. 导入第三方软件库

sudo add-apt-repository ppa:jonathonf/python-3.6

可能会出现

add-apt-repository commod not found

只需敲入以下命令解决：

sudo apt-get install software-properties-common python-software-properties

3. 更新软件源并安装

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install python3.6

4. 将默认的python 链接指向python3.6

cd  /usr/bin/
sudo ln -s python3.6 /usr/bin/python

补充：安装pip

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
