How to Fix LaTeX Missing Package in RStudio for MacOS

LaTeX configuration in RStudio

Problem

When I’m trying to knit .Rmd file into .pdf file in RStudio, I’ve got this error log:

/Applications/RStudio.app/Contents/MacOS/pandoc/pandoc t.utf8.md — to latex — from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash-implicit_figures — output t.pdf — filter /Applications/RStudio.app/Contents/MacOS/pandoc/pandoc-citeproc — template /Users/13k/R/rmarkdown/rmd/latex/default.tex — highlight-style tango — latex-engine pdflatex — variable geometry:margin=1in
output file: t.knit.md

pandoc: Error producing PDF from TeX source.
! LaTeX Error: File `framed.sty’ not found.

Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: sty)

Enter file name:
! Emergency stop.
<read *>

l.31 \definecolor

Error: pandoc document conversion failed
Execution halted

The main problem is:
File ‘framed.sty’ not found.

Solution

After a few hours of googling time for a solution, I’ve found that it was caused by missing LaTeX package in my macOS. Unlike LaTeX in Windows, I can’t find GUI app for LaTeX in macOS. Because of that, I need to do package installation manually using Terminal with sudo tlmgr command.

Try to type this command in Terminal:
sudo tlmgr update — self
sudo tlmgr install framed

You may need this LaTex version have been installed on your Mac:
XeLaTeX
MiKTeX
