【问题描述】：

我正在尝试部署我在 Rshiny 中制作的应用程序，因为这几天不成功......在本地它工作得很好......当我尝试发布到 Shinyapps.io 帐户时出现唯一问题......

我将包全局加载（在 apps.r 脚本中）为：

加载所需的包

mLoad <- function(...) 
  sapply(sapply(match.call(), as.character)[-1], require, character.only = TRUE)


mLoad(cluster,plyr,dplyr,DT,data.table,ggfortify,ggcorrplot,ggraph,ggplot2,ggthemes,imputeTS,knitr,markdown,purrr,randomForest,rCharts,reshape2,rpivotTable,rsconnect,shiny,shinythemes,shinyapps,tibble,tidyr,tidyverse,vegan,VIM,visdat)

我在部署时遇到以下错误.....

据我所知，所有必需的软件包都已从 CRAN 或 Github 本地安装......仍然不知道为什么我收到上述错误......

某些包之间似乎存在冲突....无法弄清楚在哪里....

【参考方案1】：

解决了 Shiny 部署问题......只需将库名称放在 rpivotTableOutput("mypivot") 的 ui 部分中，如下所示......

rpivotTable::rpivotTableOutput("mypivot")..

事实上，即使在部署后，许多功能也无法正常工作（本地应用程序可以无缝运行）....对于 dplyr 的 ex...rename()，即使在加载 dplyr 库之后......只需将函数前面的库名称....dplyr::rename().....必须为应用程序中的许多功能做......在server以及闪亮代码的ui部分......
