The error when publishing a shiny app

Question

I want to publish my shiny app. For this I created an account in https://www.shinyapps.io/ Then, in RStudio, I go to Tools->Shiny Apps->Publish Apps and paste the token, account and secret information. Finally, I get the error:

Error: /v1/users/current/ 426 - shinyapps package out of date.
 To update visit: https://github.com/rstudio/shinyapps

When I try to install "shinyapps", the following message occurs:

install.packages("shinyapps")
Error in install.packages : Updating loaded packages

Restarting R session...

Error in tools:::httpdPort <= 0L : 
  comparison (4) is possible only for atomic and list types

Answer 1

As the error message says, please install shinyapps from https://github.com/rstudio/shinyapps It is not a package on CRAN, so you cannot install.packages().
