I was trying for two hours to simply change the font family to a Sans Serif font, but whatever I try it will always end up with serifs...
My setup is a Mac with Pandoc installed. I want to use markdown files to create PDFs. Within the file I setup a YAML block with my desired options. However I can not find a font installed which is Sans Serif.
I use this:
--- title: bla fontfamily: merriweather ---
However this never works out, I get merriweather with serif font. If I try to set 'merriweathersans' it will throw the error message: "merriweathersans.sty" not installed. However with sudo tlmgr install merriweathersans I can not find this package to install anyway.
And all other Sans Serif packages I try always end in total disaster (like fontfamily: arev; this will end in a 'LaTeX Error: This NFSS system isn't set up properly.'
