This probably happens because R removes empty directories during build. We could probably subvert it by adding a single empty file or something similar? Or by creating that directory on demand rather than expecting it to exist.

I don't have a great idea on the other issues, though. :-/

The other failures had skip_on_travis but that doesn't work in GHA. They now have skip_on_ci as of https://github.com/rstudio/packrat/pull/638.

Sadly, we now see:

══ Failed tests ════════════════════════════════════════════════════════════════
── Failure (test-dependencies.R:58:3): dependencies are discovered in inline R code ──
"emo" %in% packrat:::fileDependencies(emojiRmd) is not TRUE

`actual`:   FALSE
`expected`: TRUE 
── Failure (test-rmarkdown.R:22:3): We can discover dependencies with an evaluate hook ──
`deps` not equal to c("abc", "def", "ghi", "jkl").
target is NULL, current is character

Unlike the others, these failures do not happen in local "check" runs.
