Node和NPM

Node和NPM

下载地址:https://nodejs.org/en/download/

查看node版本

node -v 

C:\Users\username>node -v
v12.16.0

安装完成Node应该自带了NPM了,在控制台输入npm -v查看

npm -v

C:\Users\username>npm -v
6.13.4

npm默认的仓库地址是在国外网站,速度较慢,建议大家设置到淘宝镜像。但是切换镜像是比较麻烦的。推荐一款切换镜像的工具:nrm

我们首先安装nrm,这里-g代表全局安装

npm install nrm -g

通过nrm ls命令查看npm的仓库列表,带*的就是当前选中的镜像仓库:

C:\Users\username>nrm ls

  npm -------- https://registry.npmjs.org/
  yarn ------- https://registry.yarnpkg.com/
  cnpm ------- http://r.cnpmjs.org/
* taobao ----- https://registry.npm.taobao.org/
  nj --------- https://registry.nodejitsu.com/
  npmMirror -- https://skimdb.npmjs.com/registry/
  edunpm ----- http://registry.enpmjs.org/

通过nrm use taobao来指定要使用的镜像源:

C:\Users\username>nrm use taobao


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

通过nrm test npm来测试速度:

C:\Users\username>nrm test npm

npm ---- 1668ms
