Hi, I get similar error, while I was installed ggplot2, after an update of it;
could you please help me?
thanks in advance


Error in dyn.load(file, DLLpath = DLLpath, …) :

unable to load shared object ‘/Library/Frameworks/R.framework/Versions/3.2/Resources/library/rlang/libs/rlang.so’:

dlopen(/Library/Frameworks/R.framework/Versions/3.2/Resources/library/rlang/libs/rlang.so, 6): Library not loaded: /Library/Frameworks/R.framework/Versions/3.5/Resources/lib/libR.dylib

Referenced from: /Library/Frameworks/R.framework/Versions/3.2/Resources/library/rlang/libs/rlang.so

Reason: Incompatible library version: rlang.so requires version 3.5.0 or later, but libR.dylib provides version 3.2.0

In addition: Warning message:

package ‘ggplot2’ was built under R version 3.5.2

Error: package or namespace load failed for ‘ggplot2’

It looks like you installed a new version of R (3.5) on top of a previous version (3.2).

reference: https://community.rstudio.com/t/every-libraries-failed-to-load-after-upgrading-r-to-3-6-0/29736/21

If you’ve recently updated your R version, it will look for your installed libraries in a new directory, e.g., R/x86_pc_linux-gnu-library/3.6 (where previously you used, e.g., R version 3.4). On Windows platforms, there is a hand function to move all your installed libraries over to the new directory. For MacOS and Linux platforms, many libraries need to be compiled from source.

Try updating your packages with
update.packages(repos='http://cran.rstudio.com/', ask=FALSE, checkBuilt=TRUE)

Thanks very much for your amazing quick replay;
very useful;
I’ve checked my current version which is 3.2;
unfortunately from this directory : Library/frameworks/R.frameworks/versions/
I could see only 2 folder , label 3.2 and current;

Do you have any Idea I could uninstall the 3.5 , which actually “shadow” the 3.2

thanks again

Afraid I don’t know how to uninstall the 3.5, have you tried to update the R packages under 3.5?

update.packages(repos=‘http://cran.rstudio.com/’, ask=FALSE, checkBuilt=TRUE)

you can also change the version of R that RStudio uses back to 3.2
