Not able to use 'caret' package

General
1

Hi,
I need to use confusionMatrix function so I've downloaded 'caret' package.
At the end of the installation the following errors appear:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
ERROR: compilation failed for package ‘gower’

  • removing ‘/Library/Frameworks/R.framework/Versions/4.0/Resources/library/gower’
    Warning in install.packages :
    installation of package ‘gower’ had non-zero exit status
    ERROR: dependency ‘gower’ is not available for package ‘recipes’
  • removing ‘/Library/Frameworks/R.framework/Versions/4.0/Resources/library/recipes’
    Warning in install.packages :
    installation of package ‘recipes’ had non-zero exit status

The downloaded source packages are in
‘/private/var/folders/13/0q4ppkzs6rbbmd2g73dkgk180000gn/T/RtmpZs0Y2z/downloaded_packages’

I'm working on mac. I've deleted R and R studio and installed again, deleted the package and installed again. Restarted R server. Anything works.
Finally when using confusionMatrix or any function of this package, I receive an error indicating that the function can't be found.
Could you please assist?

If you need to install from source, then you need to install Xcode in your system (not in R) and the recommended development tools for macOS systems.
