从官网下载最新python3.8
解压至本地文件夹
进入文件夹
为了避免出现问题，我们先提前安装第三方库
sudo update sudo apt-get install -y libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev build-essential libssl-dev zlib1g-dev
特别是libreadline不安装的话会出现上下左右和退格键无法使用的情况
编译至/usrlocal/python3.8
./configure --prefix=/usr/local/python3.8 make make install
软连接至/usr/bin/下
sudo ln -s /usr/local/python3.8/bin/python3.8 /usr/bin/python3.8
接下来shell输入python3.8进入python3.8解释器
