knitr broken

[ken.kn...@inserm.fr]

I think that I broke knitr somehow on one of my laptops (because it still works on the other one).  For any rmarkdown document that I try to compile either using Rstudio or the Mac GUI, I get the following error message:

processing file: ExpML.Rmd

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

  ICU init failed: U_FILE_ACCESS_ERROR

Calls: <Anonymous> ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>

Execution halted

I tried reinstalling R, knitr and several of its dependencies.  I note that I can't compile the latest version of knitr on my Mac either currently. So the currently installed version is 1.10.5.  I get the error message for every file that I have tried, including old ones that did work so that is why I don't have a minimal example.  I don't know what I did or how to fix it.  Any suggestions as to where to look next would be much appreciated.  Thank you.

Here is my sessionInfo() from an Rstudio session.

It appears you will need to reinstall the stringi package:

install.packages('stringi')

If this does not install the Mac binary package of stringi but
compiles the package from source instead, you may have to reinstall or
upgrade Xcode.
