Question

我正在尝试部署Shinyapp，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sessionInfo：

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

这是再现错误的最小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，您必须先使用以下命令安装medulloPackage：

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

使用此软件包时出现错误，因此不确定如何处理。

Answer 1

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

在您的代码中，我添加了几行：

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

这是完整的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)

我列出了我采取的步骤，也许您已经同意其中的一些步骤：

安装medullo-classifier-package

我必须手动安装这两个软件包：

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

通过以下方式安装BioManager：

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