bug with multiple R versions, missing RTools on Windows

[olivroy]

I have 2 versions of R installed on Windows.

R 4.2.3 + RTools42 R 4.3.0 (No RTools)

When running with R 4.3.0 an installation

pak::pak("r-lib/usethis")
✔ Loading metadata database ... done                      

→ Will update 1 package.
→ The package (0 B) is cached.
+ usethis 2.1.6 → 2.2.2.9000 [bld][cmp] (GitHub: 467ff57)

! usethis is loaded in the current R session, you probably need to restart R after the installation.

Maybe I am mistaken and this is an intended behaviour.

Can you install packages with pak from GitHub without RTools installed? Because remotes::install_github("r-lib/usethis") worked.

You cannot currently, because pkgbuild checks for RTools, even if the package does not need compilation.

Because remotes::install_github("r-lib/usethis") worked.

Because that probably does not use pkgbuild.

duplicate of #165. I didn't realise I was using an older version of pkgbuild

Closing as duplicate of #165 thanks!

You cannot currently, because pkgbuild checks for RTools, even if the package does not need compilation.

If it is planned that pak uses pkgbuild unconditionally for this, it may be worth adding some doc to pak to warn about this, as tidyverse advertises pak more in README pages.

Fortunately, with pkgbuild 1.4.2 the instructions are more clear :)

Edit: I just saw that you may want to change this in r-lib/pak#225
