Question

我的Shiny应用程序一直运行到上周。我正在尝试运行应用程序，并在大多数情况下收到错误：下面是错误和我的sessionInfo。

我正在使用Shinydashboard和其他闪亮的库来渲染应用程序。

Error in withReactiveDomain(shinysession, { :

Answer 1

上周发布了闪亮版0.14.2（以及R和RStudio的新版本）。也许这破坏了代码中的某些内容。防止这种情况的一种方法是使用packrat包之类的东西锁定某个版本的R包，这样您的代码就不会被新包更改。然后，您可以在使用该新版本之前针对升级测试代码并进行故障排除。

Answer 2

重启R studio工作。没有必要更新任何软件包。
