Mac下 node安装、配置及踩坑

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

1. 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
2. 保存网页名为：brew_install.rb，保存位置随意，但要能找到
3. 在终端输入$curl

4. 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
   

   在等待安装homebrew时，出现问题LibreSSL SSL_read: SSL_ERROR_SYSCALL, errno 54
   fatal: the remote end hung up unexpectedly

==> Tapping homebrew/core
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...

Error: Failure while executing; `/usr/local/bin/brew tap homebrew/core` exited with 1.
Failed during: /usr/local/bin/brew update --force

• 解决办法，按步骤执行

// 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

// 更新
brew update

// 使用
brew install node

最终大功告成
