Ubuntu 22.04 Release DateUbuntu22 还有几个月就要来到了，自带的 Python 版本将是 3.10 ，但是我想在 Ubuntu20.04 上也想用呢！
Ubuntu 22.04 Jammy Jellyfish is scheduled for release on April 21, 2022
【Ubuntu20.04 从源代码编译安装 python3.10】If you’re ready to use Ubuntu 22.04 Jammy Jellyfish, you can either upgrade your current Ubuntu system or download Ubuntu 22.04 and install it from ISO.
Ubuntu20.04 自带的 Python 版本是 3.8 ，如果想安装 python3.9 可以用该命令：
sudo apt install python3.9
Ubuntu20.04 的仓库没有收录 python3.10 ，那我们就自己从源码编译安装吧！准备工作，先安装依赖项
sudo apt update
sudo apt upgrade
sudo apt install gcc
sudo apt install g++
sudo apt install libffi-dev
sudo apt install build-essential checkinstall
sudo apt install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev我把 python3.10 源码压缩包下载到下载 Python 源代码 到~/Downloads目录下
我把 python3.10 安装到~/opt目录下
~/opt 目录下执行下面的命令下载源代码的压缩包sudo curl -O https://www.python.org/ftp/python/3.10.1/Python-3.10.1.tgz解压缩
tar zxvf ./Python-3.10.1.tgz查看
╭─bot@amd-5700G ~/Downloads

6439619 .rw-rw-r--125M48952 botbot2 Jan 13:58Python-3.10.1.tgz准备好安装路径
cd ~/opt
mkdir python3.10.1安装
cd ~/Downloads/Python-3.10.1
sudo ./configure --enable-optimizations --prefix=/home/bot/opt/python3.10.1
sudo make -j8
sudo make install默认只用一个处理器编译，这太慢了，我们多进程并行处理：sudo make -j8 && make install,-j8 表示用 8 个处理器，如果你的处理器只有4个就改成4安装好了就是下面的样子
