闪亮的runExample错误-无法创建服务器 [英] Shiny runExample Error - Fail to create server

问题描述

我正在尝试使用Shiny，只是尝试运行基本的现成示例.没有骰子.

I am trying to play around with Shiny and simply attempted to run the basic out-of-the-box example. No dice.

我尝试过Google问题，但是在外部服务器上运行该问题时，一切似乎都可以解决.

I attempted to Google the Issue but everything appears to address issues when running it on an external server.

也许我弄错了，但我认为该应用程序可以使用localhost在我的浏览器中运行.

Maybe I am mistaken, but I assumed that this app would run in my browser using localhost.

这是我所做的:

install.packages("shiny")
library(shiny)
runExample("01_hello")

这是错误:

> runExample("01_hello")

Listening on port 8100
Error in startServer("0.0.0.0", port, httpuvCallbacks) : 
  Failed to create server

为了完整起见，这是我的会话信息:

and for completeness sake, here is my session Info:

推荐答案

@哈德利(Hadley)重新安装shiny和httpuv的最后评论起到了作用.

@Hadley's last comment to re-install shiny and httpuv did the trick.

 devtools::install_github(c("shiny", "httpuv"), "rstudio")
