It may be the same question as this, however it stood unanswerd
我确实有同样的问题,我无法加载库“shinydashboard”。我发现了上面的问题,但解决方案仅针对Ubuntu / Linux。我正在使用RStudio和Windows,无法使用该解决方案。
我的代码:
## app.R ##
install.packages("shinydashboard")
library(shiny)
library(shinydashboard)
ui <- dashboardPage(
dashboardHeader(),
dashboardSidebar(),
dashboardBody()
)
server <- function(input, output) { }
shinyApp(ui, server)
我收到以下错误消息:
库中的错误(shinydashboard): 没有名为'shinydashboard'的包
将install.packages中的lib参数更改为
install.packages("shinydashboard",lib="C:/Program Files/R/R-3.4.1/library")
我收到以下错误: 是的:

对于否:

Error in install.packages : unable to install packages
Error in library(shinydashboard) :

答案 0 :(得分:0)
正如@Roland所提到的,软件包已安装到错误的库中(仅适用于我自己的用户帐户)。在尝试将其安装到另一个库并出现写访问问题后,我最终手动将该文件夹复制到第二个(可供所有用户使用)库。
