Are you running Windows? I had this problem and followed the steps here for Windows:

You need to download this certificate file, browse to your ruby installation directory and copy it to ..lib/ruby/"your ruby version"/rubygems/ssl_certs/

If you have troubles downloading it like I did, you can just create a file named AddTrustExternalCARoot-2048.pem and copy the contents of the certificate file in your browser to the file you created.

Make sure to save with the extension to .pem and allow windows to change it.
