在 docker 上安裝本地 R 庫時遇到問題

Question

我正在嘗試在 docker 上部署我的 Shiny 應用程序（使用 rocker/shiny-verse:3.6.3 基本映像），但是當我嘗試通過 Z05B6053C41A213EAFZ6 安裝本地（非 CRAN）軟件包時遇到問題。 在 RStudio 內完成安裝工作正常。

• Docker 引擎 v19.03.13

• 操作系統：Windows 10 企業版

成功 - 當我嘗試在 RStudio 中安裝本地 package 時：

> install.packages("<FULLPATH>/customLibrary.zip", repos = NULL, type = "win.binary")
WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

https://cran.rstudio.com/bin/windows/Rtools/
Installing package into ‘C:/Users/p/Documents/R/win-library/3.6’
(as ‘lib’ is unspecified)
package ‘customLibrary’ successfully unpacked and MD5 sums checked

---

Dockerfile

FROM rocker/shiny-verse:3.6.3
RUN R -e "install.packages('<FULLPATH>/customLibrary.zip', repos = NULL, type = 'win.binary')"
RUN R -e "install.packages(c('gtable', 'data.table', 'shinydashboard', 'ggplot2'), repos='https://cran.rstudio.com', dependencies=FALSE)"
COPY . /srv/shiny-server
EXPOSE 3838

失敗 - 當我使用上述 Dockerfile 構建我的 Docker 映像時：

有人能指出我哪里出錯了嗎？ TIA。

Answer 1

在 RStudio 中，您開發 package，安裝 devtools 然后運行

devtools::build(binary = FALSE)

它將生成可以安裝在任何平台上的 tar.gz package。

這是文檔： https://rdrr.io/cran/devtools/man/build.html

Answer 2

rocker-org/shiny的 dockerfile 建立在 Debian 之上。

這是 Shiny 服務器上的 Dockerfile 穩定版。

請參閱GitHub和DockerHub -這里是 dockerfile。

這意味着對您的 OP 的評論是正確的。 您正在嘗試在 linux 上安裝 windows 二進制文件，但這不起作用。 因此，您的問題就在這里。

install.packages("<FULLPATH>/customLibrary.zip", repos = NULL, type = "win.binary")

我想解決方案是為 linux 編譯您的customLibrary並簡單地做

install.packages("<FULLPATH>/customLibrary.zip", repos = NULL)
