package or namespace load failed for ‘tidyverse’ in namespaceExport(ns, exports): undefined exports: %>%

I was helping someone get up and running with R/RStudio today, and we struggled to get the tidyverse to load. We tried uninstalling/re-installing R/Studio/packages but no luck. I've never come across this issue before. What's the best way to troubleshoot?


Error: package or namespace load failed for ‘tidyverse’ in namespaceExport(ns, exports):

Did you check all the packages are up to date? Maybe there's a version incompatibiity.

%>% comes from the magrittr package, check that this is loaded ok.

I've encountered the same problem with "tidyverse" and with the "pool" package. I cannot load the packages properly without loading "magrittr" first. My main problem is, that I cannot check my package build due to this error or even load a package via devtools::load_all().

Any solutions so far?


Thanks @woodward. It's a fresh install of R/RStudio and first time downloading tidyverse. sessionInfo() shows the correct magrittr version too.
