dplyr not loading

[aliceal]

When I am trying to load dplyr, it is saying that rlang is the wrong version. I have removed rlang and reinstalled it then checked its version which is 1.0.2 which should be sufficient. This is on juypter notebook.

Error: package or namespace load failed for ‘dplyr’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
namespace ‘rlang’ 0.4.11 is already loaded, but >= 1.0.0 is required

how did you check the rlang version ? what you say disagrees with your error message...
The implication I suppose is that you need to restart R to notice a change in installed rlang version given if rlang is loaded then its version can't change. Try restarting ?

I used packageVersion("rlang").

Its weird I've tried restarting.

ok lets check the restart behaviour.
When you restart, immediately after run ls() and sessionInfo() to look at your session.
Mine is like this

> ls()
character(0)
> sessionInfo()
