以前，发光的应用程序在软件包和RStudio服务器（发光（1.3.2）和httpuv（1.5.1））更新之前可以完美运行。运行该应用程序后，该应用程序的页面立即变为灰色。
我已经尝试过此https://community.rstudio.com/t/shiny-v1-3-known-regressions-and-serious-issues/28180/4，但仍然无法正常工作。 我也尝试过此https://stackoverflow.com/a/27113322/10004051，但确实可以，但是我不想包含这些额外的代码。
错误示例：
shiny::runExample("01_hello")
此解决方法可以解决此问题：
runExample("01_hello", host="0.0.0.0", port=9999)
这是我的会话信息：
