安裝 Node

注意：如果沒有FQ默認源可能安裝npm失敗，請參考下一節“安裝 NPM”修改鏡像源地址。

• 查看可用版本： nvm ls available
• 安裝Node：
  nvm install [version]
• 指定使用版本： nvm use [version]

安裝 NPM

　　nvm全稱Node Version Manager是 Nodejs 版本管理器，它讓我們能方便的對 Nodejs 的版本進行切換。

　　使用默認源可能安裝npm失敗，需要修改../nvm/settings.txt文件，添加如下配置。

root: C:\dev\nvm path: C:\dev\nodejs arch: 64 proxy: none node_mirror: http://npm.taobao.org/mirrors/node/npm_mirror: https://npm.taobao.org/mirrors/npm/

安裝NRM

　　nrm(npm registry manager)是npm的鏡像源管理工具，有時候國外資源太慢，那么我們可以用這個來切換鏡像源。

• 安裝nrm npm install nrm -g

• 查看可用鏡像源 nvm>nrm ls* npm ---- https://registry.npmjs.org/cnpm --- http://r.cnpmjs.org/taobao - https://registry.npm.taobao.org/nj ----- https://registry.nodejitsu.com/rednpm - http://registry.mirror.cqupt.edu.cn/npmMirror https://skimdb.npmjs.com/registry/edunpm - http://registry.enpmjs.org/
• 選擇使用鏡像源 nrm use taobao
