强迫症患者发现远程服务器的python版本不够update。 最新的python版本是3.8.2。 找到一个教程：https://tecadmin.net/install-python-3-8-ubuntu/

安装以下包，用于compile最新的python。 sudo apt-get install build-essential checkinstallsudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev \ libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev zlib1g-dev

然后去下载python 3.8.2，并解压cd /optsudo wget https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tgzsudo tar xzf Python-3.8.2.tgz

https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tgz

make 并安装 cd Python-3.8.2sudo ./configure –enable-optimizations sudo make altinstall

检查版本： python3.8 -V Python-3.8.2

删除掉安装包：cd /opt sudo rm -f Python-3.8.2.tgz
