使用NVM管理Node - Windows
安装 NVM
NVM 下载：https://github.com/coreybutler/nvm-windows
安装 Node
注意：如果没有FQ默认源可能安装npm失败，请参考下一节“安装 NPM”修改镜像源地址。
- 查看可用版本：
nvm ls available
- 安装Node：
nvm install [version]
- 指定使用版本：
nvm use [version]
安装 NPM
nvm全称Node Version Manager是 Nodejs 版本管理器，它让我们能方便的对 Nodejs 的版本进行切换。
使用默认源可能安装npm失败，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/
安装NRM
nrm(npm registry manager)是npm的镜像源管理工具，有时候国外资源太慢，那么我们可以用这个来切换镜像源。
- 安装nrm
npm install nrm -g
- 查看可用镜像源
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/
- 选择使用镜像源
nrm use taobao
NVM 命令

Optionally specify whether to install the 32 or 64 bit version (defaults to system arch).
Set [arch] to "all" to install 32 AND 64 bit versions.
Add --insecure to the end of this command to bypass SSL validation of the remote download server.
