放几个阿里云的优惠链接 代金券 / 高性能服务器2折起 / 高性能服务器5折

添加 puppeteer

npm i --save puppeteer

• 安装时会因为国内外网屏蔽导致下载失败出现

ERROR: Failed to download Chromium r515411! Set "PUPPETEER_SKIP_CHROMIUM_DOWNLOAD" env variable to skip download. 

可以使用国内镜像解决，参考

npm config set puppeteer_download_host=https://npm.taobao.org/mirrors
npm i puppeteer
