我想测试renv
闪亮的应用程序包。这是我的虚拟应用程序:
library(pool)
library(fresh)
library(shiny)
ui <- fluidPage(
titlePanel("Old Faithful Geyser Data"),
sidebarLayout(
sidebarPanel(
sliderInput("bins",
"Number of bins:",
min = 1,
max = 50,
value = 30)
),
mainPanel(
plotOutput("distPlot")
)
)
)
server <- function(input, output) {
output$distPlot <- renderPlot({
x <- faithful[, 2]
bins <- seq(min(x), max(x), length.out = input$bins + 1)
hist(x, breaks = bins, col = 'darkgray', border = 'white')
})
}
shinyApp(ui = ui, server = server)
请注意,我只加载了 2 个库pool
而不fresh
使用它们。
init()
包中的命令renv
正在我的项目路径上创建一个本地库:
renv::init("/home/z0044uca/mytest_renv/")
* Initializing project ...
* Discovering package dependencies ... Done!
* Copying packages into the cache ... [21/21] Done!
The following package(s) will be updated in the lockfile:
# CRAN ===============================

Restarting R session...
* Project '~/mytest_renv' loaded. [renv 0.12.5]
我的问题是如何将应用程序部署到我的闪亮服务器而不在服务器上安装两个包(pool
和fresh
)。
当我将整个文件夹 ( mytest_renv
) 复制到我的服务器并尝试在浏览器中运行应用程序时,我收到以下错误(在log
文件中)
Warning message:
The following package(s) are missing entries in the cache:
base64enc, BH, commonmark, crayon, DBI, digest, fastmap,
fresh, fs, glue, htmltools, httpuv, jsonlite, later,
magrittr, mime, pool, promises, R6, rappdirs, Rcpp, rlang,
rstudioapi, sass, shiny, sourcetools, withr, xtable
These packages will need to be reinstalled.
Error in loadNamespace(name) : there is no package called ‘digest’
Calls: local ... loadNamespace -> withRestarts -> withOneRestart -> doWithOneRestart

我期待renv
我的应用程序目录中的文件夹负责所有包和依赖项。
