Answer 1

Concluding from the comments and from my own experience the problem often seems to be that some TeX fonts are missing, most often

• inconsolata.sty and
• upquote.sty

First you have to find the right directory where TeX fonts are stored - in my case this is:

C:\Program Files\R\R-3.3.0\share\texmf\tex\latex

Then you can download them here:

• https://www.ctan.org/tex-archive/fonts/inconsolata/?lang=en
• https://www.ctan.org/tex-archive/macros/latex/contrib/upquote?lang=en

Just copy them to the respective folder and in many cases the problem will be solved (in my case too). This should work for all operating systems.
