Shinydashboard: 'restoreInput' is not an exported object from 'namespace:shiny'

问题

I am using RStudio to create a new Shiny app. I copy and paste the code sample from https://rdrr.io/cran/shinydashboard/man/renderValueBox.html into the app.R. I receive this error:

Warning: Error in : 'restoreInput' is not an exported object from 'namespace:shiny'
Stack trace (innermost first):
    45: getExportedValue

    42: inherits
    41: tagAssert
    40: dashboardPage
     1: runApp
Error : 'restoreInput' is not an exported object from 'namespace:shiny'

Here is my sessionInfo() output:

UPDATE: 1) I tried the sample from a different machine and produced the same error. 2) I also took a shinydashboard skeleton app and reproduced this error.

回答1:

Ran update.packages() and newer versions didn't have this issue.
