Error: package or namespace load failed for ‘tidyverse’ in loadNamespace

问题

I'm getting the following error when I'm loading tidyverse. It was all working fine a few minutes ago when I was running my shinyapp. How should I resolve this?

Error: package or namespace load failed for ‘tidyverse’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]): namespace ‘rlang’ 0.3.0.1 is already loaded, but >= 0.3.1 is required

I had the same problem but managed to tackle it. You may remove the current version of rlang using the following command:

remove.packages("rlang")

and then install the rlang again:

install.packages("rlang")

After that run the library:

library(tidyverse)

I know this is an old question but I faced this same problem. I restarted R session and it worked fine after that. Hope this helps someone! :)

Also had similar problem but resolved it after a struggle. I used:-

devtools::install_github("tidyverse/tidyverse")
