我正在做闪亮的教程，就像在https://shiny.rstudio.com/tutorial/written-tutorial/lesson1/上解释的那样
在某个时候，我必须运行示例应用程序。示例应用程序存储在文件夹/usr/local/lib/R/site-library/shiny/examples/01_hello 中，我想在终端中运行它。所以我输入
sudo -i R # entering my password so that R is being started
library(shiny)
runApp("/usr/local/lib/R/site-library/shiny/examples/01_hello")
但它不起作用。
我的控制台给了我以下错误信息：
Listening on http://127.0.0.1:3530

此处不支持在常规用户会话中以 root 身份运行 Firefox。（$XAUTHORITY 是 /run/user/1000/gdm/Xauthority，归基数所有。）我发现了 firefox 问题，但与 R 无关...
我的目标是在输入runApp()Firefox 后分别打开一个新选项卡并显示闪亮的应用程序，以便我可以与之交互。
另外我不得不说，我是 ubuntu 的新手——所以在回答我的问题时请记住这一点。提前谢谢了！
Shiny 使用高范围 (>1024) 的 TCP 端口，所以这里不需要
sudo。以可以访问 Xorg 的普通用户身份执行所有命令：
