Answer 1

Try upgrading your SSL certificates.

1. Download http://curl.haxx.se/ca/cacert.pem

2. Save this file anywhere you want, such as:

   C:\cacert.pem
   

3. On the command line, tell Ruby where to find the cert file, such as:

   set SSL_CERT_FILE=C:\cacert.pem
   

4. Try again.

   gem install compass
   

5. If it works, you can make the cert file permanent by adding it in your control panel.
