Devtools installation failed

[NavidGhazna]

Hi, I am pretty new to rstudio. Wanted to install devtools but it it shows an error which I dont understand. Would appreciate if someone could help.

library(devtools)
Error: package or namespace load failed for ‘devtools’:
.onLoad failed in loadNamespace() for 'pkgload', details:
call: loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]])
error: namespace ‘rlang’ 0.4.12 is already loaded, but >= 1.0.1 is required
In addition: Warning message:
package ‘devtools’ was built under R version 4.1.3

Try to install through terminal...

:$ sudo su - -c "R -e \"install.packages('devtools', repos='https://cran.rstudio.org', lib='/usr/lib/R/library', dependencies = TRUE, INSTALL_opts = '--no-lock')\""

error: namespace ‘rlang’ 0.4.12 is already loaded, but >= 1.0.1 is required

This is asking you to update the rlang package

install.packages("rlang")

If you get an error message while doing this, please post it here to give you further advice.

Thanks a lot. I did update the rlang package and it worked.

Thanks for the reply. As andresrcs said I update rlang and it worked.
