r - Rmarkdown won't knit to HTML xcrun: error on mac

Question

I recently switched from a pc to a macbook (running big sur 11.0.1) and just installed R studios yesterday. I'm working in R and I get this error when I try to knit to an HTML:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Quitting from lines 15-18 (thesis_analyses.Rmd) 
Error in View(sp) : X11 dataentry cannot be loaded
Calls: <Anonymous> ... withCallingHandlers -> withVisible -> eval -> eval -> View
Execution halted

Has anyone had this issue before?

The closest solution I could find was here, but I wanted to see if anyone had encountered the same issue or could confirm this would fix my problem before proceeding. I get real nervous messing around in my terminal without guidance...

Thank you in advance!

Answer 1

So I did need to install the command line tools, but I also needed to install XQuartz before I could use the knit function. Now it works!
