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
