Windows下安装及更新NodeJS和NPM

nodejs

1. 安装nodejs，直接通过官网的msi安装包安装即可；

2. 升级nodejs，直接重新下载新版本，安装会覆盖更新。

3. node -v

// 注意：设置npm镜像，不要使用cnpm

npm config set registry https://registry.npm.taobao.org –global

npm config set disturl https://npm.taobao.org/dist –global

npm

1.安装npm，默认包含在nodejs的安装包中，通过安装nodejs实现安装npm(可能版本不是最新)；

2.更新npm，通过使用第三方包管理更新 npm-windows-upgrade 链接

升级注意：only use this tool to upgrade npm, do not attempt to run npm install npm

PowerShell as Administrator
