Question

我在ubuntu服务器上安装了闪亮的服务器。我在开发服务器上做了类似的安装工作。当他们打开R会话加载一些包。该应用程序在本地运行正常，但我收到的消息是，它在发光服务器上运行时找不到包。

应用上的错误

During startup - Warning messages:

1: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE,  :
  there is no package called ‘shiny’
2: package ‘shiny’ in options("defaultPackages") was not found 
3: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE,  :
  there is no package called ‘data.table’
4: package ‘data.table’ in options("defaultPackages") was not found 
5: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE,  :
  there is no package called ‘optiRum’
6: package ‘optiRum’ in options("defaultPackages") was not found 
Error in eval(expr, envir, enclos) : 
  The Shiny package was not found in the library. Ensure that 
Shiny is installed and is available in the Library of the 
user you're running this application as.

在Rprofile.site中我有

# ## Example of Rprofile.site
 local({
#  # add MASS to the default packages, set a CRAN mirror
  old <- getOption("defaultPackages"); r <- getOption("repos")
#  r["CRAN"] <- "http://my.local.cran"
  options(defaultPackages = c(old, "shiny","data.table","optiRum"), repos = r)
})

.First <- function() {
   cat("\n   Welcome to R!\n\n")
#    setwd("/home/OPTIMUMCREDIT/R/Projects")
    Sys.umask(mode="0002")
}
.libPaths(c("/home/R/WorkingPackages","/home/R/ApprovedPackages"))

在闪亮的服务器配置中，我只有默认配置（因此运行为闪亮和默认端口）。

我的sessionInfo（）

我尝试在代码中添加一条消息来输出library(shiny)上面的libPaths，但遗憾的是发生了相同的错误消息。我做了一些卸载和重新安装，因为我有点不寻常地安装了闪亮的服务器，然后记得我需要闪亮但没有快乐。我已经确认在ApprovedPackages中安装了闪亮。加载的软件包，我希望能够绕过这个问题或者找到更多的信息。

更新 - 以闪亮的方式运行 啊 - 情节变浓了......用户在控制台上闪亮登录会导致应用程序获得相同的警告，并且.libPaths（）与其他人不一样：

我有点难过，并希望有人能指出我正确的方向来解决问题。

对不起烦恼。您可以尝试运行以下命令来安装Shiny系统范围吗？

sudo su - \
  -c "R -e \"install.packages('shiny', repos='http://cran.rstudio.com/')\""

这来自Admin Guide，它（希望）将成为这类问题的有用资源。

我怀疑问题是Shiny确实已正确安装在您的用户帐户中，但由于它未安装为sudo，因此<{1}}用户无法。< / p>

编辑：

当shiny用户启动R进程时，您还需要确保正在应用Rprofile.site。您可以登录shiny：

来执行此操作

shiny

然后打开R并检查sudo su shiny或查看是否可以在那里成功运行.libPaths()。如果您无法做到，那么让library(shiny)用户进入您的共享包目录或您的shiny文件（或其父目录）可能存在问题。确保将Rprofile.site用户添加到必要的组中，或者这些文件及其所有父目录为shiny用户授予适当的权限。
