When trying to build my Github Pages site locally, the jekyll-github-metadata plugin is causing SSL cert errors. The site has no problem rendering on github pages, so it must be a configuration issue on my end.
I am aware of this issue, and while it does not appear to be exactly the same (I have no trouble installing gems, only using the github metadata plugin) I added the certificate to my environment variables, but it changed nothing.
What do I need to change for the SSL cert to verify properly?

Following the instructions from here, I managed to get it working.
Download the cacert.pem file from http://curl.haxx.se/ca/cacert.pem. Save this file to C:\RailsInstaller\cacert.pem.
Now make ruby aware of your certificate authority bundle by setting SSL_CERT_FILE. To set this in your current command prompt session, type:
set SSL_CERT_FILE=C:\RailsInstaller\cacert.pem
