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.pem
Then set my environmental variable "SSL_CERT_FILE" to "C:/RubyCertificates/cacert.pem"

证书地址：http://curl.haxx.se/ca/cacert.pem

按照上面这位网友的方法配置了环境变量如下图

再次执行gem sources -a https://ruby.taobao.org/
报错依旧

有谁遇到过，还是我的环境变量没有配置对呢？

Answer 1

现在淘宝的gem停止更新维护了，目前是ruby-china维护。
gem source --remove https://ruby.taobao.org/ --add http://gems-china.org/

Answer 2

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

Answer 3

遇到同样问题，按照https://gist.github.com/fnichol/867550 的步骤执行后顺利通过（需要注销机子）。
不过我是添加到系统变量，不知道是不是这个原因。

Answer 4

要添加到系统变量，重启电脑再执行切换淘宝源的命令就可以了
