I had this same issue while working on a Ruby project. I am using Windows 7 64bit.I resolved this by:Downloading the cacert.pem file from http://curl.haxx.se/ca/cacert.pem.Saved that file to C:/RubyCertificates/cacert.pemThen set my environmental variable 'SSL_CERT_FILE' to 'C:/RubyCertificates/cacert.pem'source: https://gist.github.com/fnichol/867550

證書地址：http://curl.haxx.se/ca/cacert.pem

按照上面這位網友的方法配置了環境變量如下圖

再次執行gem sources -a https://ruby.taobao.org/報錯依舊

有誰遇到過，還是我的環境變量沒有配置對呢？

問題解答

現在淘寶的gem停止更新維護了，目前是ruby-china維護。gem source --remove https://ruby.taobao.org/ --add http://gems-china.org/

gem source --add http://rubygems.org/gem source -l

遇到同樣問題，按照https://gist.github.com/fnichol/867550 的步驟執行后順利通過（需要注銷機子）。不過我是添加到系統變量，不知道是不是這個原因。

要添加到系統變量，重啟電腦再執行切換淘寶源的命令就可以了
