coderay not working on github page about minimal-mistakes

[mmistakes]

It's been a while since I tried using Coderay. I believe you need to switch from Pygments to Coderay under the Kramdown settings in _config.yml.

Also I don't think GitHub Pages support Coderay. It appears it's either Pygments or Rouge.

Github pages runs on a minimal configuration. The details of installed dependencies and versions are listed here.

As CodeRay is not installed, if you try to build directly from Github, it is not going to tokenize your code blocks. There is an easy workaround for this, just build your site locally where it will generate the proper tokens and maintain the actual build on your username.github.io repository.
