修改参数

PS D:\Program files\nodejs> mkdir node_global
PS D:\Program files\nodejs> mkdir node_cache
PS D:\Program files\nodejs>
PS D:\Program files\nodejs> npm config set prefix "D:\Program Files\nodejs\node_global"
PS D:\Program files\nodejs> npm config set cache "D:\Program Files\nodejs\node_cache"

npm install 的时候总是为sill状态，修改为淘宝URL源

PS D:\Program files\nodejs> npm config set registry https://registry.npm.taobao.org  

2、安装puppeteer
