docker-ubuntu 安装python3.8,pip3

制作docker是，需要下载python3.8。

更换国内源

vim /etc/apt/sources.list

注释之前的，然后添加：

deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
##测试版源
deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
# 源码
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
##测试版源
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
# Canonical 合作伙伴和附加

更新：

apt-get update

安装依赖包

apt-get install software-properties-common

添加 deadsnakes PPA 源

add-apt-repository ppa:deadsnakes/ppa

4.下载python3.8

 apt-get update
 apt-get install python3.8

5.建立软链接

先删除旧的python连接。

删除后建立新的连接关系，例如linux下python3默认在/usr/bin/下

sudo rm -rf /usr/bin/python
ln -s /usr/bin/python3.8 /usr/bin/python

6.输入pip会找不到pip模块，这时候需要重新下载pip

进入python3.8的lib中：

cd /usr/lib/python3.8
wget https://bootstrap.pypa.io/get-pip.py  --no-check-certificate
python get-pip.py

然后，安装成功！！
