I am teaching with Rstudio.cloud for the first time and so far it has been great. But we ran into a problem today with knitting. Many people had to update a bunch of packages today to make the knit work. That's fine. But for one person, the packages are not loading. Specifically, it wanted updated versions of knitr, stringr, and rmarkdown. They clicked the yes button to update. But it didn't work. After much playing around, I discovered that the stringi package (part of stringr, at least) was not loading and we got the error that it had "non-zero exit status". I have tried everything I can think of or find on the web. I've removed the packages and reinstalled them. I've reloaded the project and reinstalled. I tried installing with "win.binary" and it said it can't do that on this platform (I assume the cloud). I'm not a techy, so I'm sorry, if there is an easy answer that I've missed. The project in question is: https://rstudio.cloud/spaces/24707/project/470465.
Unfortunately we teach on a very condensed system - we'll be done with this course in 3 weeks (having covered a semester of material in 3.5 weeks), so any quick answers would be very, very appreciated. Thanks!
Edited to add that this student can knit in a different project in their workspace. The problem appears to be just in this project.
