## we can prune them now:
cache_prune()
#> Delete 229 pin versions, freeing 218M ?
#> Error in utils::menu(c("Yes", "No")): menu() cannot be used non-interactively

Interactively, I can now say "Yes" and then the pruning works. 👍

Unless I am mistaken, I don't think we are testing this caching code anywhere in the package. Let's consider how we might test that in a separate issue/PR and only focus on fixing this bug here.

Do you know why this behaves differently? I wouldn't have expected this code to give a different result, so something about my understanding of dir_ls() is flawed.

[juliasilge]

I think it's that recurse = 2 goes down 2 levels and the old code just went down one:

fs::dir_ls(type = "directory")
#> R         blog      inst      man       revdep    tests     tools     vignettes
fs::dir_ls(type = "directory", recurse = 1)
