python3.5 升级到python3.6

1. 安装python3.6

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
如果执行update时报403错误:
执行 sudo add-apt-repository ppa:deadsnakes/ppa, 重新update
sudo apt-get install python3.6

2. 删除python3.5的pip

apt-get remove python3-pip
apt-get autoremove

3. 安装python3.6版本的pip

apt-get install python3-pip
rm /usr/bin/python3
ln -s /usr/bin/python3.6 /usr/bin/python3
python3.6 -m pip install --upgrade pip

4. 查看python版本

pip -V

亲测有效.
