Fails to install if repo is not named "CRAN"

[xguardi]

Installation failed bc:

current_cran <- getOption("repos")["CRAN"]
returned NA

I had to manually add to my .RProfile a repo labelled CRAN:

`options(repos = c("CRAN" = "http://cran.r-project.org"))

as in my case it was labelled differently: 'RStudio'. In any case, cran repos can have other names as well, or you might be using also a corporate one.
`
This is the code that generated the error when Mason tried to install the server

r-languageserver/src/install.r

Line 10 in 16ec4a6

if (current_cran == "@CRAN@")

Cheers,
