Answer 1

单独保留python2 macos本机安装，可能某些系统实用程序需要它。
如果您需要自制软件来安装python3，请执行以下操作：

macOS Requirements

64位Intel CPU 1
macOS High Sierra（10.13）（或更高版本）
用于Xcode的命令行工具（CLT）：xcode-select --install, developer.apple.com/downloads or Xcode
用于安装的Bourne兼容外壳（例如bash或zsh）

然后在命令行上：

如here所示：

 $ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

或根据推荐的there：

mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew

安装homebrew后，您可以brew install python3，如here所述

注意：

pip install homebrew将从pipy安装一个python软件包，您可以从python导入该软件包。 IDK该软件包的作用，但有可能它是一个使用python来帮助生成brew installable应用程序的实用程序-可能不是您想要的！
