2.下载Python3
wget https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tgz
3.安装python3
创建目录：
mkdir -p /usr/local/python3
解压下载好的Python-3.x.x.tgz包：
tar -zxvf Python-3.8.2.tgz
4.进入解压后的目录，编译安装。
cd Python-3.8.2
./configure --prefix=/usr/local/python3 && make && make install
5.建立python3的软链
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
6.并将/usr/local/python3/bin加入PATH
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
export PATH
source ~/.bash_profile
7.检查Python3及pip3是否正常可用：
python3 -V
Python 3.8.2
pip3 -V
pip 9.0.1 from /usr/local/python3/lib/python3.6/site-packages (python 3.6)
