摘要：在macOS系统中安装Python 2.7和Python 3.x多个版本，可以使用pyenv这一Python多版本管理工具来实现。通过简单的安装步骤，pyenv可以轻松管理不同版本的Python，并允许在同一系统上同时使用多个Python版本。这种方法适用于新版macOS系统，使用户能够方便地安装和使用Python多版本。

在新版本的macos中已经将默认的python升级成了3.x , 今天介绍一个简单的方法在新版本的macos中快速安装 python 2.7的方法, 就是使用brew安装python版本管理工具 pyenv来安装python2.7

# 安装pyenv版本管理工具
brew install pyenv
# 安装python2.7 可以安装多个版本的ptyhon
pyenv install 2.7.18
