[R-pkg-devel] Cannot implement test configuration

[Hüsing, Johannes]

Thanks, Ivan. Here is a transcript of the session. Note that functions from the usethis package are invoked from devtools::test(), experts of which I figured I might find most likely here.

Best wishes

Johannes

What's the traceback() output immediately after this error happens? If you post it, someone may be able to point out the offending code and perhaps find a way to convince it to use the drive letter instead of the UNC path.

Since the error is encountered by code in 'usethis' (or somewhere downstream), likely not in base R, you may also get a more direct answer by following links at <https://usethis.r-lib.org/SUPPORT.html>.
