Trouble Installing: "There is no package called 'rlang'"

[Wyspr]

I've installed swirl with the command

install.packages("swirl")

When I type

library("swirl")

Error: package or namespace load failed for ‘swirl’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called ‘rlang’

I then tried

install.packages("rlang")

There is a binary version available but the source version is
later:
binary source needs_compilation
rlang 0.2.0 0.2.1 TRUE

Do you want to install from sources the package which needs compilation? (Yes/no/cancel)
installing the source package ‘rlang’

Does anyone have any suggestions?

I restarted RStudio but that didn't help. I used install.packages("dplyr") (reinstalled the package) and that worked for me (the 'rlang' error didn't show up anymore). Hope this helps someone. :)

This works. I use microsoft open R and rstudio. Did this and it solved the problem.

Dplyr seems to cause a whole bunch of problems with other packages, including ggplot for the same rLang dependancy.

I just uninstalled it and it solved this problem entirely.

I had the original issue that was posted, and tried install.packages("dplyr") only to get the same issue with rlang.

installation of package ‘rlang’ had non-zero exit status.

To preface, I don't know anything about swirl.

I found this thread when trying to fix a similar problem, and updating all installed packages seemed to fix the problem for me.

I have also had this problem in the past. I fixed this by deleting the rlang file in ~\Documents\R\win-library\4.0, then reinstalling rlang from RStudio, which allowed me to successfully install and update the packages which were previously triggering this error.

This is legit. Did this and it solved the problem.

This install.packages("dplyr") solved to me on version 4.1.1 (2021-08-10). Thank you very much

please sir ,try another way:download directly from CRAN,and choose the version(4.1.1) for your R(4.1.1),
