To build an R package from source fails: Win10, RStudio - r

Question

Installing a package from source fails for me on my windows machine. I uninstalled RStudio, R and deleted rtools40 folder, restarted and reinstalled those items. I believe I have the path set up appropriately.
Here's the code I tried, using some troubleshooting help from here:
#troubleshooting installation
pkgbuild::find_rtools()
pkgbuild::has_rtools(TRUE)
pkgbuild::check_rtools(TRUE)
pkgbuild::rtools_path()
pkgbuild::check_build_tools(TRUE)
pkgbuild::check_compiler(TRUE)
Sys.getenv("PATH")
Sys.getenv('BINPREF')
sessionInfo()
#Test installation from source via CRAN
pkgbuild::with_build_tools(install.packages("lme4", type = "source"))
And here is the output:
Restarting R session...

Answer 1

This is more of a work around than a proper answer. The alternative to installing and building from source is to install a pre-built binary. If one is not available, you can build it remotely.
In this case, for the package of interest for me, rundel/livecode on github, I:
Forked the repo (in this case rundel/livecode). This step might be optional.
Downloaded the tar.gz (remotes::install_github("markbneal/livecode") which doesn't install it, but the error tells you where it saves the .tar.gz file locally.
Used rhub to build the package binary for windows, go to this website https://builder.r-hub.io/ and upload your tar.gz file, ensuring rhub has your email address (click "advanced" button to provide your email address as alternate - you will need to validate it). That emails me a zip 5 minutes later.
Then copy the livecode folder in the zip that is emailed to me to my "R packages" folder location.
Package should now work for you, in my case library(livecode)
Edited six months later when I had to use this process again!
