r - 将 Shiny 应用程序部署到 shinyapps.io 时出现问题

Question

运行以下代码将一个非常简单的 Shiny 应用程序部署到shinyapps.io：

rm(list = ls())

library(shiny)
library(rsconnect)

ui <- fluidPage("Hello World",
                sliderInput(inputId = "num",
                            label = "Choose a Number",
                            value = 25,
                            min = 1,
                            max = 100),
                plotOutput("hist"))

server <- function(input, output)
{

  output$hist <- renderPlot({
    hist(rnorm(input$num))
  })

}

shinyApp(ui = ui, server = server)

rsconnect::setAccountInfo(name='xxx redacted xxx', token='xxx redacted xxx', secret='xxx redacted xxx')
rsconnect::deployApp(".") # we're already in the correct directory

它不工作。我可以从shinyapps.io仪表板中看到该应用程序，但是当我尝试在我的网络浏览器中启动它时，我会看到一个旋转的轮子并最终显示一条消息：

Attaching package: ‘rsconnect’

The following object is masked from ‘package:shiny’:

serverInfo

Error in value[[3L]](cond) : HTTP 409 POST https://api.shinyapps.io/v1/applications/2371290/deploy Unable to dispatch task for application=2371290, there are 1 tasks in progress Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous> Execution halted

出现。有人可以帮忙吗？我以前从未这样做过，我有点困惑。

运行 Microsoft R 客户端 3.5.2/RStudio 1.3/Windows 10。

谢谢你。
