Mac下安装node环境，这里介绍的只是其中一种
1、打开终端，输入/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"安装管理平台homebrew
/usr/bin/ruby -e "$(curl -fsSL [https://raw.githubusercontent.com/Homebrew/install/master/install](https://raw.githubusercontent.com/Homebrew/install/master/install))"
执行之后报错curl: (7) Failed to connect to raw.githubusercontent.com port 443: Operation

这里说明一下，有些同学针对出现此错误的解决办法是：重装command line tools，再执行安装指令，然鹅，我自己试了一下，对我没用。。。。
终端报错图片 解决办法
- 在浏览器输入地址https://raw.githubusercontent.com/Homebrew/install/master/install
打开如下：
打开地址图片 - 保存网页名为：brew_install.rb，保存位置随意，但要能找到
- 在终端输入$curl
-
在终端进入存放brew_install.rb(上面保存的文件)的目录，然后运行$ruby brew_install.rb
步骤

// 执行命令，更换为中科院的镜像：
git clone git://mirrors.ustc.edu.cn/homebrew-core.git/ /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1
// 把homebrew-core的镜像地址也设为中科院的国内镜像
cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
