Answer 1

RubyGems从您配置的源(存储在〜/ .gemrc中)中获取gem.默认来源是https://rubygems.org.

但您可以执行以下命令:*

gem sources --remove https://rubygems.org/
gem sources --add http://rubygems.org/

^{────────────
*如果您想重置为" 出厂设置 ":
       gem sources --remove http://rubygems.org/
       gem sources --add https://rubygems.org/}

Answer 2

这很可能是由于运行与rubygems.org的安全(https)连接.查看"gem sources -h"的帮助,删除https版本并添加http://rubygems.org
