    1. Check out pyenv where you want it installed.A good place to choose is $HOME/.pyenv (but you can install it somewhere else).
    • 检查要安装的pyenv, $HOME/.pyenv是一个不错的选择(使用git命令之前需要先安装git)
    sudo apt install git
    git clone https://github.com/pyenv/pyenv.git ~/.pyenv
    
    1. Define environment variable PYENV_ROOT to point to the path where pyenv repo is cloned and add $PYENV_ROOT/bin to your $PATH for access to the pyenv command-line utility.
    • 定义环境变量"PYENV_ROOT"指向克隆pyenv repo的路径,然后将" $PYENV_ROOT / bin "添加到$PATH 中以访问pyenv命令。
    echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
    echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
    
    1. Add Pyenv init to your shell to enable shims and autocompletion .Please make sure eval "$(pyenv init -)" is placed toward the end of the shell configuration file since it manipulates PATH during the initialization.
    • 在shell中添加Pyenv init以启用填充和自动补全功能。请确保将eval "$(pyenv init-)"放在shell配置文件的末尾,因为它会在初始化过程中操纵* PATH *。
    echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.bashrc
    
    1. Restart your shell so the path change take effect. You can now begin using pyenv.
    • 重新shell,以使路径更改生效。 您现在可以开始使用pyenv。
    exec "$SHELL"
    
    1. Install Python build dependencies before attempting to install a new Python version.
    • 在尝试安装新的Python版本之前,请先安装Python构建依赖项。
    sudo apt-get update; sudo apt-get install --no-install-recommends make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev
    
    1. Install Python versions into $(pyenv root)/versions.
    • 将Python版本安装到$(pyenv root)/ versions中。
    pyenv install 2.7.8
