Problem opening the Shiny file

[Hugomorais]

...Hello community.
I'm working on RStudio and I need to open a new Shiny file, but the following message appears.

I clicked yes, then the following error message appears.

In
*** arch - i386
Warning in system(cmd) : 'make' not found
ERROR: compilation failed for package 'fastmap'

• removing 'C:/Users/hugo_/OneDrive/Documentos/R/win-library/3.6/fastmap

Does anyone know how to solve this problem?

I installed Rtool and the problem was solved.

Thanks, Andresrcs.

If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] :information_s…
