我有一个Shiny应用程序，它使用server.R文件中的以下包。
library(shiny) #Creating the app
library(ggplot2)
library(plyr)
library(reshape2)
library(scales)
library(grid)
library(data.table)
library(pracma)
library(dplyr)
应用程序在Rstudio中运行时没有任何错误;但是，当我尝试上传它时，它给出了一个错误（下面）。似乎该错误与dplyr包有关。我删除dplyr包时成功上传。我需要dplyr和plyr包在server.R脚本中进行一些计算。
N.B。 server.R和ui.R的脚本很长，很难包含在这里的问题中。
有没有人有过类似的问题？这里出了什么问题，怎么处理呢？
这是我在上传Shiny应用程序后在Rstudio中遇到的错误：
library(rsconnect)
library(shinyapps)

Error: Unhandled Exception: Child Task 84820936 failed: Error building image: Error building dplyr (0.4.3). Build exited with non-zero status: 1
答案 0 :(得分：1)
我找到了解决问题的方法。 dplyr包需要安装Rcpp包。首先安装Rcpp包然后部署应用程序。
install.packages("Rcpp")
deployApp()
成功上传！
