使用指令 gem sources -a https://ruby.taobao.org/
提示以下資訊:
Error fetching https://ruby.taobao.org/:
SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://rubygems-china.oss-cn-hangzhou.aliyuncs.com/specs.4.8.gz)
建議使用ruby-china的gem源,這個ruby-china的原來維護淘寶的gems的都不在淘寶了,現在搞了一個
https://gems.ruby-china.org/
https停止維護了,用http吧!
