Error when trying to deploy the 'KoNLP' package.

When I try to publish an app on 'shinyapps.io' using the "KoNLP" package, I get the following error:

Error in value[[3L]](cond) : there is no package called ‘KoNLP’
Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Execution halted

'shinyapps.io' does not seem to support the 'KoNLP' package.

library(KoNLP)

Without this package, no error is generated. my OS is Windows
I am a beginner in this matter.
Please let me know what I should do to use the package. Please be specific.

Use the console pane

library(KoNLP)

If it loads, then yes, you probably have a shiny problem.

But if it throws the error message

Error in library("KoNLP") : there is no package called ‘KoNLP’

then you need to

install.packages("KoNLP")

I just did this on Mojave without problem; Ubuntu and friends should also be ok. About Windows, I can't say since I so seldom use it.
