I can't knit my documents into PDF in RStudio

Question

I have to use RStudio to knit a report in PDF but when I try to knit the document with the packages required in a chunk in Rmarkdown it shows me this error:

tlmgr search --file --global '/multirow.sty'

tlmgr: Remote repository is newer than local (2018 < 2019)
Cross release updates are only supported with
  update-tlmgr-latest(.sh/.exe) --update
Please see https://tug.org/texlive/upgrade.html for details.
! LaTeX Error: File `multirow.sty' not found.

! Emergency stop.

Inoltre: Warning message:
In system2("tlmgr", args, ...) :

Execution interrupted

how can I fix this? I am using a MacBook Pro

I tried to updated everything I can and I've tried to install everything from the beginning but it jeeps showing me the same error message

To wrap the comments to the question up and following the solution at Yihui Xie's page - see also here for a discussion.

In short ...

tinytex::reinstall_tinytex()

... should do the trick.

Explanation: It seems that {tinytex}/Texlive is using a rolling package repository that moves to a new version each year while the local installment does not. The reinstallation does move the local installment forward.

An alternative solution: There seems to be an alternative solution that involves making the TexLive package repo un-rolling - i.e. using a fixed version - which might help: link
