Hello,
I have updated r to the latest version.
When I reinstalled the packages, I installed devtools (with dependencies), however, when I want to use this package, I get the following error:
install.packages("devtools")
trying URL 'https://cran.rstudio.com/bin/macosx/contrib/4.0/devtools_2.3.2.tgz'
Content type 'application/x-gzip' length 337605 bytes (329 KB)
==================================================
downloaded 329 KB
The downloaded binary packages are in
/var/folders/k6/6hcwnkcn099frbhql59cjg900000gn/T//RtmpuPFy8Z/downloaded_packages
library("devtools", lib.loc="/Library/Frameworks/R.framework/Versions/4.0/Resources/library")
Loading required package: usethis
Error: package or namespace load failed for ‘devtools’:
.onLoad failed in loadNamespace() for 'pkgload', details:
call: loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]])
error: there is no package called ‘rprojroot’
Could you please help me understand what's wrong?
Thanks in advance
