CentOS系統升級Python版本有以下幾種方法：
sudo yum install centos-release-scl。sudo yum install rh-python38。scl enable rh-python38 bash。python --version。curl https://pyenv.run | bash。export PATH="$HOME/.pyenv/bin:$PATH" eval "$(pyenv init --path)" eval "$(pyenv init -)"添加到~/.bashrc或~/.zshrc文件中，然后source ~/.bashrc或source ~/.zshrc。pyenv install 3.8.10。pyenv global 3.8.10。python --version。sudo yum groupinstall "Development Tools"，sudo yum install openssl-devel bzip2-devel libffi-devel zlib-devel readline-devel sqlite-devel。wget https://www.python.org/ftp/python/3.x.x/Python-3.x.x.tgz，然后解壓。./configure --enable-optimizations，make -j 8（8可根據CPU核心數調整），sudo make altinstall。python3.x --version。
