python3.5升级到3.6

第一步：

sudo apt-get install software-properties-common

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

sudo apt-get update

sudo apt-get install python3.6

强制安装报错：

E: Unable to locate package python3.6-dev
E: Couldn't find any package by glob 'python3.6-dev'
E: Couldn't find any package by regex 'python3.6-dev'

解决办法：安装python3.6

方法1

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.6

方法2

sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6

使用pip -V查询，发现pip还是python3.5的pip，如何指向python3.6呢，首先是删除pip

apt-get remove python3-pip

apt-get autoremove

然后是安装pip

apt-get install python3-pip

发现pip还是指向 python3.5的，这个时候再用python3.6指定升级一下pip：

python3.6 -m pip install --upgrade pip

然后再输入pip -V命令查询pip版本
