Hi @WillBeethoven ,

It seems to be network issue.
puppeteer/puppeteer#1597

Well, I struggled with this issue for two hours this morning. After running npm install -g cnpm --registry=https://registry.npm.taobao.org and cnpm i puppeteer, I thought it should work but failed at login with the access error. So I downloaded nvm to avoid writing access error. Then running cnpm install -g github-uploader.

Finally, it works.
