ERROR: Could not find a valid gem 'sass' (>= 0) in any repository
1 我執行了gem sources --remove https://rubygems.org/?成功了
2 我執行?gem sources -a https://ruby.taobao.org/?失敗了錯誤如下
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 我試圖將remove掉的源添加回來，執行了：gem sources --add https://rubygems.org/
但是報錯，錯誤信息和第二步是一樣的

域名備案問題，現在要改成這個。gem sources --add http://gems.ruby-china.com/ --remove?https://rubygems.org/

我試了很多都不行，這個可以gem sources --add http://gems.ruby-china.org/ --remove https://rubygems.org/? ??
然后再執行gem install sass
