After updating to MacOS Catalina, RStudio no longer works, so I upgraded the latter to v 1.2.5019.
Now, when I try to knit an Rmd file, I'm told: "Rendering R Markdown documents requires an updated version of the digest package. Do you want to install this package now?"
When I select Yes, I get a window appearing too briefly for me to read. Something appears to be installing, but when I try once again to Knit, the whole cycle repeats.
Installing "digest" manually results in the same loop.
Any suggestions? Thanks in advance.
