I wrote a Shiny App with R Shiny, I created an account on Shinyapps.io and every step worked with
rsconnect::deployApp('/path/to/my/app') open a new window where my app is supposed to be displayed.
The problem is that shinyapps cannot load the packages I used in my code.
The error message is :
An error has occurred
The application failed to start (exited with code 1).
Le chargement a nécessité le package : readxl
Warning in library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
aucun package nommé ‘readxl’ n'est trouvé
(I just put the warning for one package but there's the same for every one of them)
What should I do ?
