Rshinyapps.io部署应用程序时出错：无法确定Bioconductor包图的包源

Question

我正在尝试部署闪亮的应用程序，但出现以下错误：

> deployApp()
Preparing to deploy application...
Update application currently deployed at
https://komalrathi.shinyapps.io/medulloclassifiershinyapp/? [Y/n] Y

In addition: Warning messages:

2: invalid gid value replaced by that for user 'nobody'

这是我的会话信息：

[6] jsonlite_1.6       packrat_0.5.0      openssl_1.4.1      askpass_1.1   

这是重现错误的最小 app.R 代码：

library(shiny)
library(shinydashboard)
library(medulloPackage)

ui <- dashboardPage(
  dashboardHeader(title = "Classifier"),
  dashboardSidebar(
  ),
  dashboardBody(
  )
)

server <- function(input, output) {
}

shinyApp(ui, server)

在运行之前，您必须首先medulloPackage使用以下命令进行安装：

devtools::install_github("d3b-center/medullo-classifier-package")

当我使用这个包时出现错误，所以不知道如何处理它。

Answer 1

经过一些步骤后，我猜应用程序现在可以正确加载：看看https://abenedetti.shinyapps.io/medullo/

我从你的代码中添加了几行：

library(BiocManager)
options(repos = BiocManager::repositories())

这里是完整的app.R文件：

library(shiny)
library(shinydashboard)
library(medulloPackage)

library(BiocManager)
options(repos = BiocManager::repositories())

ui <- dashboardPage(
    dashboardHeader(title = "Classifier"),
    dashboardSidebar(
    ),
    dashboardBody(
    )
)

server <- function(input, output) {
}

shinyApp(ui, server)

我列出了我所采取的步骤，也许您已经同意其中的一些步骤：

1. 安装medullo-classifier-package

我必须手动安装这两个包：

install.packages("digest")
install.packages("rlang")

2. 安装BioManager：

   if (!requireNamespace("BiocManager", quietly = TRUE)) install.packages("BiocManager") BiocManager::install()
