Errors in publishing a Shiny app using leaflet.extras package (Couldn't normalize path in addResourcePath)

[cpuzhoulili]

Hello,

I am creating a Shiny app which creates maps using leaflet package, and I also used leaflet.extras to get rid of background color of the maps. I am using R version 3.6.0 in Windows. It works on my computer, but when I tried to publish my app on a Shiny open server (Linux system), I got an error below:

Warning: Error in value[[3L]]: Couldn't normalize path in addResourcePath, with arguments: prefix = 'map-widget-style-1.0.0'; directoryPath = 'C:/Program Files/R/R-3.6.0/library/leaflet.extras/htmlwidgets/build/map-widget-style' 106: stop 105: value[[3L]] 104: tryCatchOne 103: tryCatchList 102: tryCatch 101: addResourcePath 100: FUN 99: lapply 98: renderWidget 97: transform 96: func 94: f 93: Reduce 84: do 83: hybrid_chain 82: origRenderFunc 81: output$leaflet1 1: runApp

Maps don't show up in the app. Could anyone please help me figure out what is the problem and how to fix it? Thank you very much!

Can you reinstall leaflet.extras on the server? Something went obviously wrong there, as R is looking in the directoryPath for the files, but C:/Program Files is definitly not a Linux filepath :)
