I created a new Rmd file in the latest R and Rstudio version, and with the complete version of MiKTeX installed. In my windows 10 machine.
When I tried to knit it I got the following error
! LaTeX Error: File `fancyvrb.sty' not found.
Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: sty)
Enter file name:
! Emergency stop.

I suspected that it could have been that I didn't have the package fancyvrb in MiKTeX , so I followed these instructions but I still get the same error.
Try the same using
Miktex package manager (admin)
Under > repository check that your package repository is up to date.
In the name box type the name of your package
Then filter
then add your package
To test if your package is installed in dos CMD type kpsewhich fancyvrb.sty. you should be able to see the path to your package.
