    $ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
    $ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
    
    $ echo 'eval "$(pyenv init -)"' >> ~/.bash_profile
    
    $ exec $SHELL
    Copy after login

  • Common pyenv commands:

    $ pyenv install 2.7.6 // 安装python 2.7.6版本
    $ pyenv local 2.7.6   // 这个应用使用2.7.6版本
    $ pyenv global 2.7.6  // 全局环境版本
    
    $ pyenv versions // 列出已经安装的所有版本,*表示当前环境正在使用的版本
          2.5.6
