R markdown will not knit

General

Since updating to RStudio: 1.1.447 and R: 3.5.0, I get the following error message when I try to knit a document to HTML -
Error in library.dynam(lib, package, package.lib) :
shared object ‘stringi.so’ not found
Calls: :: ... tryCatch -> tryCatchList -> tryCatchOne ->
Execution halted

The same error occurs with all documents.

Reinstall the stringi package.

Actually if you upgraded R to 3.5.0, chances are you need to reinstall all your packages (update.packages(ask = FALSE, checkBuilt = TRUE)).

That worked. Thank you so much.
