ERROR: Could not find a valid gem 'sass' (>= 0) in any repository

源自：2-2 Sass安装（windows版）

1 我执行了gem sources --remove https://rubygems.org/ 成功了

2 我执行 gem sources -a https://ruby.taobao.org/ 失败了错误如下

ERROR: While executing gem ... (Errno::ENETRESET)

The connection has been broken due to keep-alive activity detecting a failur

e while the operation was in progress. - recvfrom(2)

3 我试图将remove掉的源添加回来，执行了：gem sources --add https://rubygems.org/

但是报错，错误信息和第二步是一样的

ERROR: While executing gem ... (Errno::ENETRESET)
