Cannot use install.packages

Good afternoon ,
I have a problem with install.packages , for example :
install.packages("caret")
Warning in install.packages :
unable to access index for repository cran.rstudio.com/src/contrib:
scheme not supported in URL 'cran.rstudio.com/src/contrib/PACKAGES'
Installing package into ‘C:/Users/Mouad/Documents/R/win-library/3.5’

Warning in install.packages :

Warning in install.packages :

cannot open URL 'http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.5/PACKAGES'
I tried without success :
options(repos='cran.rstudio.com/')
I think the source of pb is that Rtools isn´t properly installed :
Sys.which("make")
make
""
Thank you for help !

R studio stopped working. Uninstall and re install but packages all cant be detected

I tried running a pacman package and found it could not be installed. I tried installing tidyverse package individually and it says error. Now R is not able to run since all packages cannot be installed.
Lastly, uninstalled R studio and re install but it is still facing an issue.
