Sandpaper installation on Windows error

[RicCampbell]

Hello,

I've just run through the Workbench setup for Windows, and ran into an error when building a lesson (sandpaper::build_lesson(tmp, preview = FALSE, quiet = TRUE), under 'test your installation').

I believe that it was looking in the wrong location for a tinkr stylesheet, as all packages were installed on a network drive. Installing the packages locally and updating the Renviron file seems to have worked though.

@tdjames1 can provide more information as she helpfully troubleshooted this for me.

Hi,

@RicCampbell was seeing an error like this:

xslt error: xsl:import : unable to load C://path/to/R/win-library/4.2.1/tinkr/stylesheets/xml2md_gfm.xsl

where //path/to was a resolved form of the original path, U:\path\to (which maps to a network drive).

I tracked the problem down to:
https://github.com/carpentries/pegboard/blob/e9ca729c7db3ca97f016480679f9f58d115d2721/R/get_stylesheet.R#L2
where the call fs::path_real(tinkr::stylesheet()) tries to resolve the file path to the networked drive and the resulting path cannot be located.

We thought it would be useful to raise an issue to highlight the problem for other Windows users. As @RicCampbell mentioned, we found a workaround of setting R_LIBS_USER to a local directory in the .Renviron file and reinstalling the packages.
