RStudio freaked out on me today - can't update rlang package

I need to use devtools, every time i type in library(devtools) i get this error message:

Error: .onLoad failed in loadNamespace() for 'pkgload', details:
call: loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]])
error: namespace ‘rlang’ 0.4.0 is already loaded, but >= 0.4.1 is required

I have tried multiple times to update the package. I've tried other site suggestions. To no avail.

Please help!
Thanks in advance.

Without going into the root cause of the problem, have you tried to update your package using remotes::install_github("r-lib/rlang")?

The error message is asking you to update rlang What happens when you try to update it? Do you get any error message? If so please post the whole error message here as formatted code.

install.packages("rlang")

This is what i get when trying this code:

Installing package into ‘C:/Users/Channen/Documents/R/win-library/3.6’
(as ‘lib’ is unspecified)

So, turns out I needed to install the 'lmerTest' package again....then I was able to update 'rlang'.

How silly!

Sorry, and thank you for your help!

Very unlikely that this is the cause (maybe you restarted your R session?) but nevertheless I'm glad you're issue is solved now.
