I have a problem generating a pdf report from my app shiny which is hosted on a server.
the app works fine but when I press the button to download the report, I get this error :
pandoc version 1.12.3 or higher is required and was not found.The proble is that if I type pandoc -v I get:

I'm here to give other information if needed.
