目标是将python版本从 2.7 更新到3.8
二、安装步骤
2.1 下载python3.8安装包
wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tar.xz
2.2 安装
依次执行如下步骤：
tar Jxf Python-3.8.0.tar.xz
cd Python-3.8.0
./configure prefix=/usr/local/python3
make
sudo make install
2.3 环境切换
查看目前python环境：
将python环境切换成刚刚安装的3.8
sudo rm /usr/bin/python3 sudo ln -s /usr/local/python3/bin/python3.8 /usr/bin/python3
至此安装成功！
