我正在使用 RStudio 创建一个新的 Shiny 应用程序。我将 https://rdrr.io/cran/shinydashboard/man/renderValueBox.html 中的代码示例复制并粘贴到 app.R 中。我收到此错误:

Warning: Error in : 'restoreInput' is not an exported object from 'namespace:shiny'
Stack trace (innermost first):
    45: getExportedValue
    44: ::

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

这是我的 sessionInfo() 输出:

更新:
1) 我在另一台机器上尝试了 sample ,并产生了同样的错误。
2)我还拿了一个shinydashboard骨架应用程序并重现了这个错误。

最佳答案

Ran update.packages() 和更新的版本没有这个问题。

关于r - Shinydashboard: 'restoreInput' 不是从 'namespace:shiny' 导出的对象,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/44614517/
