Warning: Error in loadNamespace: there is no package called ‘markdown’

I am recently deploying my shiny app on Shinyapps.io. But I got the following error:

Warning: Error in loadNamespace: there is no package called ‘markdown’

I did not use ‘markdown’ in my shiny app. I don't understand why ‘markdown’ package is required.

Thanks a lot.

I got the same error and resolved it by adding

library(markdown)

to my Shiny app code. Didn't actually install anything else or do anything else.

In the past it must have gotten loaded alongside another package but I'm guessing some update has changed that.

My app started having the same issue too and I am not using library(markdown), instead I am using library(rmarkdown).

The reason you did not have to install anything was because you had the package installed.
I say that because when you use library(markdown) and package is not install, RStudio will prompt you to install it.

I was prompted, installed markdown package, used library(markdown) and went away.

Strange

Update: I commented library(markdown) in my application and it is still running on shinyapp.io
Not sure why it is acting that way
