#yum groupinstall -y "Development Tools"

sudo yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-
devel

./configure --enable-optimizations --prefix=/usr/local/python3.11

make
sudo make altinstall
使用make altinstall而不是make install以避免覆盖系统默认的Python版本。

/usr/local/python3.12/bin/python3.12 --version

------------------------选择

export PATH="/usr/local/python3.11/bin:$PATH"

source ~/.bashrc

当你使用make altinstall安装Python时，Python解释器通常被安装在/usr/local/bin目录下，并且会创建一个带有版本号的软链接。

which python3.12

通常情况下，它应该位于/usr/local/bin/python3.12

更新软链接：
sudo ln -sf /usr/local/bin/python3.12 /usr/local/bin/python3
sudo ln -sf /usr/local/bin/python3.12 /usr/local/bin/python

3.验证软链接：
python3 --version

4.更新pip命令的软链接

sudo ln -sf /usr/local/bin/pip3.12 /usr/local/bin/pip3
sudo ln -sf /usr/local/bin/pip3.12 /usr/local/bin/pip
