Mac安裝Homebrew,node,npm

前言

最近開始正式使用TypeScript。考慮用typedoc這個TypeScript 文檔化工具。結果家裡的新Mac居然npm都沒有.

首先，npm是個啥？

npm在Node v0.6.x版本之後，内建于Node系統。通過npm可以協助開發者安裝、解除安裝、删除、更新Node.件，并且可以通過npm釋出自己的插件。那麼就好辦了，先安裝Node後就自帶npm了。

Node.js 是一個基于 Chrome V8 引擎的 JavaScript 運作環境。

Node.js 使用了一個事件驅動、非阻塞式 I/O 的模型，使其輕量又高效。摘自：nodejs.cn

于是乎。。

MacOS安裝xcode command line tool的兩種方法

參考：百度經驗-如何安裝command line tools

• 打開終端輸入：

  xcode-select --install

  然後點選安裝
• 登入https://developer.apple.com/download/more/ 然後下載下傳dmg安裝

Homebrew安裝

Homebrew簡稱brew，是Mac OSX上的軟體包管理工具，能在Mac中友善的安裝軟體或者解除安裝軟體。

打開終端，執行以下指令安裝Homebrew,確定xcode command line tool已經安裝，本文開頭有安裝步驟。

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
           

執行上面指令後會提示輸入系統密碼，輸入密碼繼續安裝。

l2xindeiMac:~ l2xin$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

安裝Node

brew install node
    執行以下指令檢視是否安裝成功
    node -v:檢視node版本
    npm -v：檢視npm版本
           

有人遇到問題 mac上用brew把node裝好了，卻沒有npm，很不幸，我也遇到了，怎麼辦？

建議node不用brew裝 解除安裝node，安裝包安裝

brew uninstall node
           

官方下載下傳

https://nodejs.org/dist/v11.0.0/node-v11.0.0.pkg

taobao鏡像

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。。

更新node

這是後話，以後需要再試。

解決國内NPM(node.js)安裝依賴速度慢問題

這個我倒是沒驗證,搜到的:

https://blog.csdn.net/nnsword/article/details/54096268

不知道各位是否遇到這種情況，使用NPM（Node.js包管理工具）安裝依賴時速度特别慢，後來在網上找了好久才找到一種最佳解決辦法，在安裝時可以手動指定從哪個鏡像伺服器擷取資源，我們可以使用阿裡巴巴在國内的鏡像伺服器，指令如下：

npm install -gd webpack --registry=http://registry.npm.taobao.org
           

隻需要使用–registry參數指定鏡像伺服器位址，為了避免每次安裝都需要–registry參數，可以使用如下指令進行永久設定：

npm config set registry http://registry.npm.taobao.org
           

後記

全部搞好居然已經很晚了，安裝下載下傳太慢。。有空試試改鏡像位址，再接着搞typedoc
