I want to install seuratData in r
for this i need to install and load devtools
i have installed itbut unable to load it by library.

library(devtools)
Error: package or namespace load failed for ‘devtools’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
namespace ‘cli’ 3.3.0 is already loaded, but >= 3.4.0 is required
please guide me

This is asking you to update the cli package, try with this command

install.packages("cli")

If you get any error message while doing so, please post the complete console output you get so we can take a look

I am successful in installing and loading "cli".

install.packages("cli")
library(cli)
but when I installed devtools it is done as shown
[> install.packages("devtools")
Installing package into ‘C:/Users/Ms/AppData/Local/R/win-library/4.2’
(as ‘lib’ is unspecified)
trying URL 'https://cran.rstudio.com/bin/windows/contrib/4.2/devtools_2.4.5.zip'

package ‘devtools’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
C:\Users\Ms\AppData\Local\Temp\RtmpmsTXZO\downloaded_packages]

for loading I did

library(devtools)
Error: package or namespace load failed for ‘devtools’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
namespace ‘cli’ 3.3.0 is already loaded, but >= 3.4.0 is required

I dont know how to deal with this error of namespace!
kindly guide me.

But since you get the same error message we can assume you are not successful in updating cli. Can you post the complete console output you get when you run this command?

install.packages("cli")

Close and restart R & RStudio should do it.

The update is failing because there is a lock file present, try manually removing that file before updating.
