Can't install dev version of purrr

[zoowalk]

I am unable to install the dev version of purrr, even after restarting R/RStudio etc. I am pretty sure that the package is not in use when trying install it. Yet, I get this error. Anyone else experiencing something similar? Any help? Many thanks!

Maybe you use purrr in .Rprofile?
To be really sure that purrr is not in use:

• exit all R sessions
• remove the folder purrr from your library folder
• restart you R session and do again the installation of purrr

Many thanks for your reply. It's a riddle. No, there's nothing purrr-related in my .Rprofile.
When I remove the purrr folder and try to install directly the dev / github verision I get this error.

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
  there is no package called 'purrr'

Are you able to install the dev version (if you don't mind)?

Hello @zoowalk, no help from me because I see exactly the same.

I removed purrr in the indicated way and tried to install it with

devtools::install_github("tidyverse/purrr")

Then I got an error indicating that I did not have devtools installed yet.
When I did that I saw that it also installed dependency purrr .
(I reinstalled various times and at those later times I did not see purrr reinstalled
even when I had its folder removed).

Trying to install the development versie with

devtools::install_github("tidyverse/purrr")

I get the same error as you.

It looks like a bug to me in devtools or purrr .
Maybe report it in https://github.com/tidyverse/purrr/issues ?

Many thanks for giving it a try! Will file an issue.

As @HanOostdijk said, you're getting that error because you're (a) on windows and (b) trying to install purrr when it's already loaded in an R session. You'll need to restart R/RStudio (and close any other R/RStudio instances that you have open) and try again.

If you need more diagnostics, one options to is use pak, which should detect this problem and give you specific advice:

install.packages("pak")
pak::pak("tidyverse/purrrr")

Ooooh, I just realise the problem is that devtools itself loads purrr (via usethis), so you will have to either use remotes or pak to install dev purrr on windows.
