'verbose' is not an exported object from 'namespace:R.utils'

[manomuthus]

I have been using conflicted for a while now without any issues. Recently I have been facing this issue where I get the following error message Error: 'verbose' is not an exported object from 'namespace:R.utils' This happens when I load the package mostly and sometimes when I use conflicts_prefer

[ellisp]

I have this same problem, but can see that it only happens when loading all three of httr, R.utils and conflicted. Any combination of just two of them loads fine

here's the session that doesn't work

Restarting R session...

Problem persisted even when I upgraded R and all packages. The work around is to not load R.utils, but just us :: for any functions from it I need eg R.utils::gunzip(...). I am guessing this is really an R.utils problem, although it is something about the combination of R.utils, conflicted, and httr that does it.

Looks like this is an R.utils buglet:

I've never seen this problem before.
