【问题描述】：
我正在编写一个 Dockerfile 来创建一个基于 rocker/verse:3.6.1 的 docker 映像。我需要安装 Github 上可用的 R 包，并且我需要安装来自特定提交的每个包。 我正在使用具有以下内容的 Dockerfile：
FROM rocker/verse:3.6.1
LABEL maintainer='Unknown'
RUN R -e "devtools::install_github('rstudio/renv', ref = '1584b7fccb49c2bd502ea4bdf3b7de27b0243561')"
在包含此 Dockerfile 的目录中，在 shell 提示符下输入 docker build . 后，我看到了以下输出。
docker build .

Error: Failed to install 'unknown package' from GitHub:
HTTP error 404.

Did you spell the repo owner (`rstudio`) and repo name (`renv`) correctly?
- If spelling is correct, check that you have the required permissions to access the repo.
Execution halted
The command '/bin/sh -c R -e "devtools::install_github('rstudio/renv', ref = '1584b7fccb49c2bd502ea4bdf3b7de27b0243561')"' returned a non-zero code: 1
在不使用 docker 时，我通过进入 shell 成功安装了所需的包（在所需的提交处）
R -e "devtools::install_github('rstudio/renv', ref = '1584b7fccb49c2bd502ea4bdf3b7de27b0243561')"
我也可以用这个 Dockerfile 成功构建一个 docker 镜像：
FROM rocker/verse:3.6.1
LABEL maintainer='Unknown'
RUN R -e "devtools::install_github('rstudio/renv')"
我省略了参数ref 的显式包含。但是，我仍在努力构建我需要的图像。
感谢您对这些观察结果的任何解决方案和解释。
PS - 这是我用来识别提交哈希的 R 代码：
github_lookup_commit_sha_and_date <- function(remote_pkg, date, limit = 1000){
commits_list <- gh::gh(paste0("/repos/", remote_pkg, "/commits"), .limit = limit)
commit_dates <- purrr::map(.x = commits_list, .f = function(x) lubridate::as_datetime(x$commit$author$date))
commit_shas <- purrr::map_chr(.x = commits_list, .f = function(x)x$commit$tree$sha)
tibble::tibble(commit_date = lubridate::as_datetime(unlist(commit_dates)), sha = commit_shas) %>%
dplyr::filter(commit_date < as_datetime(date)) %>%
dplyr::mutate(datetime_diff = abs(commit_date - as_datetime(date)), remote_package = remote_pkg) %>%
dplyr::filter(datetime_diff == min(datetime_diff))
}
github_lookup_commit_sha_and_date("rstudio/renv", lubridate::as_date("2019-01-01"))
PPS - 这是我在 docker 外部安装 rstudio/renv 时看到的输出。

【问题讨论】：

可以以某种方式缓存您的哈希吗？

我想这是可能的。您能否建议我如何知道它是否在本地缓存？
