vue学习1 --安装nodejs和webpack

安装nodejs

安装nrm

npm install nrm -g

安装出现错误 如下类似错误 也可能由于网速太慢的原因造成的

 # npm install时报错 npm ERR！Windows_NT 6.1.7601
...

解决方案：
执行了下面这个命令

npm --registry https://registry.npm.taobao.org info underscore

然后执行 npm install nrm -g
终于安装成功了 输入

C:\Windows\system32>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/

C:\Windows\system32>nrm use taobao


   Registry has been set to: https://registry.npm.taobao.org/

C:\Windows\system32>nrm ls

  npm ---- https://registry.npmjs.org/
  cnpm --- http://r.cnpmjs.org/
* taobao - https://registry.npm.taobao.org/

将源切到淘宝镜像上
