我无法在shinyapps.io上发布我的闪亮应用

Question

我一直试图在Shinyapps.io上部署一个闪亮的应用程序，但总是得到相同的响应：ERROR: An error has occurred. Check your logs or contact the app author for clarification.。一开始，我试着用我自己的应用程序，但我放弃了，我认为我的应用程序有一个错误。然后我从互联网上得到了一个非常简单的应用程序，只有几行代码……令人惊讶！，它没有工作。我不知道为什么，因为我遵循了所有的步骤，并且我在本地窗口上看到了这个应用程序。因此，我检查了相对路径等，没有使用任何路径。日志都没有帮助，所以我不知道还能做什么。请任何建议都可能是有用的。非常感谢

这是R闪亮代码：

ui.R

library(shinydashboard)
library(rsconnect)


setwd(dirname(rstudioapi::getActiveDocumentContext()$path))
deployApp()
ui <- dashboardPage(
  dashboardHeader(title = "Info boxes"),
  dashboardSidebar(),
  dashboardBody(
    # infoBoxes with fill=FALSE
    fluidRow(
      # A static infoBox
      infoBox("New Orders", 10 * 2, icon = icon("credit-card")),
      # Dynamic infoBoxes
      infoBoxOutput("progressBox"),
      infoBoxOutput("approvalBox")
    ),

    # infoBoxes with fill=TRUE
    fluidRow(
      infoBox("New Orders", 10 * 2, icon = icon("credit-card"), fill = TRUE),
      infoBoxOutput("progressBox2"),
      infoBoxOutput("approvalBox2")
    ),

    fluidRow(
      # Clicking this will increment the progress amount
      box(width = 4, actionButton("count", "Increment progress"))
    )
  )
)

server.R

server <- function(input, output) {
  output$progressBox <- renderInfoBox({
    infoBox(
      "Progress", paste0(25 + input$count, "%"), icon = icon("list"),
      color = "purple"
    )
  })
  output$approvalBox <- renderInfoBox({
    infoBox(
      "Approval", "80%", icon = icon("thumbs-up", lib = "glyphicon"),
      color = "yellow"
    )
  })

  # Same as above, but with fill=TRUE
  output$progressBox2 <- renderInfoBox({
    infoBox(
      "Progress", paste0(25 + input$count, "%"), icon = icon("list"),
      color = "purple", fill = TRUE
    )
  })
  output$approvalBox2 <- renderInfoBox({
    infoBox(
      "Approval", "80%", icon = icon("thumbs-up", lib = "glyphicon"),
      color = "yellow", fill = TRUE
    )
  })
}

Answer 1

解决了。我在这里发布了我如何做到这一点，以帮助任何有同样问题的人。首先，我的主要问题是没有很好地理解Dockerfile是如何工作的，所以在一些文档之后，我发现我没有添加Shiny Server所需的包。

这个页面：https://www.linode.com/docs/development/r/how-to-deploy-rshiny-server-on-ubuntu-and-debian/帮了我很多。

此外，我建议使用命令"sudo R“，并首先尝试每个R安装包，以查看每个时刻都发生了什么(我是用RStudio编写的应用程序，所以我不知道-like libssl-dev -需要哪些包)。通过这种方式，您可以轻松地查看所有日志，并能够知道哪些包没有包含在Dockerfile中，以及哪些包必须包含在Dockerfile中
