r - 使用 Dockerfile 安装 R 包

Question

我正在尝试使用 Dockerfile 安装 R 软件包。

我安装了镜像Rocker/Rstudio .

Dockerfile的内容是:

# Base image https://hub.docker.com/r/rocker/rstudio
FROM rocker/rstudio:latest

## Create directories
RUN mkdir -p /rstudio
RUN mkdir -p /rscripts


##Install R packages
RUN R -e "install.packages(c('rvest', 'jsonlite', 'data.table' ,'stringr'), repos = 'http://cran.us.r-project.org')"

然后，我通过执行以下操作构建图像:docker build -t my_r_image 。 镜像已构建，但未安装软件包，因为我收到此警告:

Installing packages into ‘/usr/local/lib/R/site-library’ (as ‘lib’ is unspecified) Warning: unable to access index for repository http://cran.us.r-project.org/src/contrib: cannot open URL 'http://cran.us.r-project.org/src/contrib/PACKAGES'

我尝试将 http://cran.us.r-project.org 替换为 = 'http://cran.rstudio.com/')"但我收到类似的错误，指出它无法访问存储库的索引。

有人知道我做错了什么吗？

edit1:请参阅我执行此操作时得到的以下输出:

.libPaths()
    [1] "/usr/local/lib/R/site-library" "/usr/local/lib/R/library"     

install.packages(c('rvest', 'jsonlite', 'data.table' ,'stringr'), repos = 'http://cran.us.r-project.org')
        Warning in install.packages :

        Installing packages into ‘/usr/local/lib/R/site-library’
        (as ‘lib’ is unspecified)

        Warning in install.packages :
          packages ‘rvest’, ‘jsonlite’, ‘data.table’, ‘stringr’ are not available (for R version 3.6.1)

Answer 1

奇怪的是，使用完全相同的 Dockerfile，我使用 rocker/tidyverse 存储库而不是 rocker/rstudio 安装软件包没有任何问题。有谁知道这是为什么吗？
