1. 从Python官网下载源代码
首先,你需要从Python的官方网站(https://www.python.org/downloads/source/)下载Python 3.10的源代码。你可以使用wget命令从命令行下载,例如:
wget https://www.python.org/ftp/python/3.10.x/Python-3.10.0.tgz
注意替换3.10.x为你想要的具体版本号。
2. 解压源代码包
下载完成后,你需要将源代码包解压到一个目录中,例如/usr/local/。你可以使用tar命令来解压,例如:
tar -xvf Python-3.10.0.tgz -C /usr/local/
3. 安装必要的依赖项
在安装Python之前,你需要确保你的系统已经安装了所有必要的编译和构建工具以及Python依赖的库。这可以通过你的Linux发行版的包管理器来完成。例如,在基于Debian的系统(如Ubuntu)上,你可以使用apt命令来安装依赖项:
sudo apt update sudo apt install -y build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev
注意,具体的依赖项可能会因你的Linux发行版而有所不同。
4. 编译和安装Python
进入解压后的Python源代码目录,并运行configure脚本来准备编译环境。你可以使用–prefix选项来指定Python的安装目录。然后,运行make命令来编译Python,最后使用make install命令来安装Python。例如:
cd /usr/local/Python-3.10.x ./configure --prefix=/usr/local/python3.10 make sudo make install
5. 验证安装
安装完成后,你可以通过运行python3.10 --version
命令来验证Python 3.10是否已成功安装并配置为系统的默认Python版本。如果一切正常,该命令将输出Python的版本号。
注意:
如果你的系统上已经安装了其他版本的Python,并且你想要使用Python 3.10作为默认版本,你可能需要更新你的系统路径(PATH)以包括新安装的Python版本。这可以通过编辑你的shell配置文件(如.bashrc或.bash_profile)并添加类似export PATH=/usr/local/python3.10/bin:$PATH的行来完成。然后,你需要重新加载你的shell配置文件或重新登录以使更改生效。
测试:
/root目录下python3默认为3.11版本
┌──(root㉿kali)-[~] └─# python3 --version Python 3.11.4
切换安装目录/usr/local/Python-3.10.0
切到安装目录/usr/local/Python-3.10.0
下,python3显示版本为3.10,更新pip
