..When I published my app to shinyapps.io, I came across the following issues:

  • PhantomJS
  • file(con, "rb"): cannot open the connection

The full log in the output pdf file:

PhantomJS not found. You can install it with webshot::install phantomjs(). If it
is installed, please make sure the phantomjs executable can be found via the PATH variable.

directory

Hi!

I'm dealing with the same issue. Have you found any solution to this?

Best!

Yes, there is a workaround:

Add this to your server.R:

if (is.null(suppressMessages(webshot:::find_phantom()))) { webshot::install_phantomjs() }
