cnpm 怎么实现unpkg.com 的效果？

自己部署一个 https://github.com/unpkg/unpkg-website ，然后启动时改下 RegistryURL https://github.com/unpkg/unpkg-website/blob/master/server/middleware/utils/getPackageInfo.js#L5

要想真跑起来光改这个还不够

1. 安装 npm install -g heroku-cli
2. 注释 server/CloudflareAPI.js 文件中的 -invariant(CloudflareEmail, "Missing the $CLOUDFLARE_EMAIL environment variable") -invariant(CloudflareKey, "Missing the $CLOUDFLARE_KEY environment variable")
