如何设置npm包管理工具的下载代理？

I solved this problem this way:

1. I run this command: npm config set strict-ssl false
2. Then set npm to run with http, instead of https: npm config set registry "http://registry.npmjs.org/"
3. Then I install packages using this syntax: npm --proxy http://username:password@cacheaddress.com.br:80 install packagename
