Mac安装Homebrew,node,npm
前言
最近开始正式使用TypeScript。考虑用typedoc这个TypeScript 文档化工具。结果家里的新Mac居然npm都没有.
首先，npm是个啥？
npm在Node v0.6.x版本之后，内建于Node系统。通过npm可以协助开发者安装、卸载、删除、更新Node.件，并且可以通过npm发布自己的插件。那么就好办了，先安装Node后就自带npm了。
Node.js 是一个基于 Chrome V8 引擎的 JavaScript 运行环境。
Node.js 使用了一个事件驱动、非阻塞式 I/O 的模型，使其轻量又高效。摘自：nodejs.cn
于是乎。。
MacOS安装xcode command line tool的两种方法
参考：百度经验-如何安装command line tools
- 打开终端输入：
xcode-select --install然后点击安装 - 登录https://developer.apple.com/download/more/ 然后下载dmg安装
Homebrew安装
Homebrew简称brew，是Mac OSX上的软件包管理工具，能在Mac中方便的安装软件或者卸载软件。
打开终端，执行以下命令安装Homebrew,确保xcode command line tool已经安装，本文开头有安装步骤。
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
执行上面命令后会提示输入系统密码，输入密码继续安装。

安装Node
brew install node
执行以下命令查看是否安装成功
node -v:查看node版本
npm -v：查看npm版本
有人遇到问题 mac上用brew把node装好了，却没有npm，很不幸，我也遇到了，怎么办？
建议node不用brew装 卸载node，安装包安装
brew uninstall node
官方下载
https://nodejs.org/dist/v11.0.0/node-v11.0.0.pkg
taobao镜像
https://npm.taobao.org/mirrors/node
l2xindeiMac:~ l2xin$ npm -v
6.4.1
l2xindeiMac:~ l2xin$ node -v
v11.0.0
l2xindeiMac:~ l2xin$
搞定了。。
升级node
这是后话，以后需要再试。

解决国内NPM(node.js)安装依赖速度慢问题
这个我倒是没验证,搜到的:
https://blog.csdn.net/nnsword/article/details/54096268
不知道各位是否遇到这种情况，使用NPM（Node.js包管理工具）安装依赖时速度特别慢，后来在网上找了好久才找到一种最佳解决办法，在安装时可以手动指定从哪个镜像服务器获取资源，我们可以使用阿里巴巴在国内的镜像服务器，命令如下：
npm install -gd webpack --registry=http://registry.npm.taobao.org
只需要使用–registry参数指定镜像服务器地址，为了避免每次安装都需要–registry参数，可以使用如下命令进行永久设置：
npm config set registry http://registry.npm.taobao.org
后记
全部搞好居然已经很晚了，安装下载太慢。。有空试试改镜像地址，再接着搞typedoc
